What are you doing, Mr. Stew? Today, let's look at the logic. Chapter 9, sequential logic by Kim Ki-soon. Sequential circuits are mentioned. When the clock of those with flip-flops jumps, we will see the actions of those. Here on the right, you can see the subscription button. Please press subscribe. Some comedy code should be here. Here, below on the right, subscription has been done. Now, those who have subscribed, please subscribe. Starting with the goal is the most important. Setting a learning goal, let's take a look at the learning goal. What is asynchronous? There are synchronous and asynchronous. Synchronous means all flip-flops operate simultaneously on the same clock. Asynchronous is when different clock signals enter, it is called asynchronous, meaning they do not operate simultaneously. If they do not operate simultaneously, it is called asynchronous, and if one clock controls all signals.

At the same time, when that happens, I call it synchronous. Then, up here, on the D flip-flop, here is a motto. Here is an asterisk. When the D flip-flop comes out, you must be able to fill out this table here. In the D flip-flop game, there are 5 inputs and outputs, right? Yes. So, the output is like this: 3Q(t) or 0, 1Q(t) or Q(t). Inputs can be like this, outputs can be like this. Let's talk about when it comes out like this under the D flip-flop. When you want to put out 0, 1, when you want to put out 1, you initialize it. If it's 00, no change, if it's 01, complement. JK is the most commonly used. In the case of SR, when Q(t) is 1 and Q(t) is 0, it becomes a reset. When Q(t) is 0 and Q(t) is 1, it becomes a set. So, when it's 00, you initialize it. If it's 01, complement. JK is the most commonly used. In the case of SR, when Q(t) is 1 and Q(t) is 0, it becomes a reset. When Q(t) is 0 and Q(t) is 1, it becomes a set.

We don't use jk much and mostly use jk. We can make the back with jk, make t, and make everything. Typically, when jk is like this, jk plu plu b, if you input like this and pull out output q, it becomes a t flip-flop. When you put 1 1 into the window, the development computer wakes up. So, it becomes t, and we will look at it after catching it. And using this, we will try to make various circuits, make high-level circuits like this, make counters, and now, if you use flip-flop synchronous, it's not synchronous, but the best experiment among the ones using flip-flops is the counter. Next, there are things like vending machines that came out before. Ultimately, looking at the previous state and the subsequent state, you need to input like this to make the previous state 2 and the subsequent state. Once you understand this,

Flip-flops and what else actually widen complaints. In our lecture on combinations that you saw, combinations do not have a clock. Therefore, the output is determined by the input, as we discussed, and we call it a sequential circuit. Sequential circuits go in order, sequentially. So, depending on the clock, actions or operations are done. We talk about sequential circuits like this. It becomes difficult synchronously depending on the timing. So now, with the clock signal, Qa and Qb change according to the clock signal. All these drawings you see are used in a 2-sequence manner. The value changes according to the clock signal. That's the idea. Take a look at it once. It might seem like a combinational circuit, but it simply determines the output based on the current input.

Then, here, the act of a memory element component, see, the previous step's output is like this again, so that it becomes one. In this way, using a clock in the previous step influences the results in the subsequent steps. Explain this characteristic in the program. Because, in the QP system, it changes the previous state as it is to QT when it is 1. It flips the previous state and sends it, right? Because of this, this is called a memory element component. It means that it is influenced by the results of the previous state. Next, here, what these guys, it doesn't matter, regardless of the previous state, they always come out as images. Even though you may not have a clear picture, in the rest of the area, when it is 5, it creates output based on the previous state. Like this, these images are actually meaningless. Oh, don't believe it, my throat is dry from talking about it.

Coffee, so you shouldn't see things like going to a coffee shop for patrol duties 60 times. Oh, you shouldn't understand things like this. Alright, then let's skip this unnecessary part. The interpretation process of the sequence circuit, step 1: Sufficient variables for circuit input and output. In this case, in circuit 4, if there are 8 circuits in total, the input should always come from the left side to the right side. The ability is on the right side, output. Then, what to do with the output? What to do, huh? Finally, it could be a Q&A called pre-play, but if you do that, what you should do in the queue is to find a break due to the reaction of some inputs at the back, right? So, combining it, the same goes for combinations. Some circuits have decreased like this, where the ending is more blocked, so if it goes to F, it becomes the output. Understanding the input, a beep may come in, or a signal may come in, right?

In Apple's eyes, what combination of a, b, and c results in f? That's the point. It's about finding the key, so when we join the Kakao Rumor, we basically eat who, 1 to 4, like this, depending on the day. We are looking for f because we are looking for a one-to-one relationship, so we declare it as ac. Here, it's the same. Therefore, we name the input and output variables and derive a Boolean algebraic expression based on clause 4. Next, we create a state table and with the state table, we create a state diagram. The state diagram represents many click counts like this. So, when 1 is inputted, it goes this way and does this, which is the state transition. By analyzing the resulting equations, we explain the circuit. That's what we are working on. So, there are three initial states in the machine. Generally, there are many ways to curse. So, from s0 to s1, there are four.

If it is entered as 1, it outputs 0, and if it becomes a circle, this kind of child sees it. Even if 1 is entered in S1, the output value is 0, and if you enter in place in English, the output value is 1. So, what is the explanation for this requirement? Make sure to have sufficient variable names. Here, there are 5 OCXs, and there is a variable X. Q&A is in Chapter 5, it was said to be an example, but when money is formed, the element is entered, and this butterfly is formed like this, so the beam is formed like this. Then, in the preform A, avoid SAR, give an app, then raise X, and put this in the limit to get the answer. So, in S, avoid SAR, X, B, A, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B, B,

Go to the internet separately and go in that way. On top of that, there's X and give it a P. So, if you go like this and go down like this, it will be fine. If you do it this way, it will be fine. The current state is currently in state 0 and 1, 0, and 111. When X comes in as 0, it first becomes 0 area like this, and it goes like this and continues like this. I'm not sure if it's green around here, but I don't know exactly, I don't know the old way, but you didn't do it like this. It's the current state, the next state, the next one will be 2X, there may or may not be. Yes, the next state, so if X is not present, it will only come out like this, and if X is present, depending on whether X is 0 or not, it will be like this now. You will simply do this, right? Then you calculate the output Y. This is related to the diagram in front. So, if it's like this, it's here. There's nothing to see so far. So, with this, we will draw the equation.

That's right. Here, the cafe takes an input and gives an output. So, what happens is, when 0 is input in the state, it gives out the reverse, and the next state is the area. This is the story. Now, when 1 is input in the state, the output is 0, and the next state is 01. This is what is shown in the picture above. It's the same. So, the current state is 00, so there are four states. It's a bit confusing, but it's 101. That's right. So, when x is 0 in the state, everything is done first. If x is 0, the next state is 00, and the output is 0. So, if 0 is input, the output is also 0, and the next state is 05. So, when 1 is input in the state, the next state is 31, and the output is 0. Let's think about the person's name. When it comes to 0 in Yeongi, it's Xeon 115. It's an ox type, and the output is 0. That's right. So, if you say x, you stay in the same place. If x is 0, the output is 0. When Yeongi is called, if x is 0, you have to hire when x is 0, and x

If the input is x equals 0, it means staying in the high output state. So, if it's x equals 1, then it's an oxide CO. If the input is x equals 1, then it becomes 000, and the output will be either 1 or 0. So, it needs to be 1. In this way, this kind of picture comes out. Now, let's go to the fashion show. With this, let's try to create the formula now. What should we make with this? It's a flip-flop. The next state is determined by the previous state. By thinking in this way, the next state is calculated. So, in this way, the next state is calculated. This is the story. So, let's try to deduce this. Actually, draw a diagram to make this. This is how it can be made. This is how the flip-flop is made. You can do it like this. By solving it this way, after the drawings, I will explain a bit. Sunlight is meaningless. 1:1. Next, we can predict the values.

There is none, I don't know, so I can meet the rest. Now, the characteristic table is in the present tense. When X R200 is entered, it changes, so the next state becomes the hero. In the current state, if it is 00, it remains unchanged, so it becomes a comfortable lead in the next round. When it is in the current state, when 0 is entered, it becomes a mix. In the current state of 0, when it is in the current state of 0, it just becomes the next state. It is just the current state, but when 3 is entered, the night state becomes 10. This is how it changes based on the current state's influence of the input. So, if the current state is 1, and 0 is entered, it becomes 2, so it just becomes a profit. When 10 is entered, it becomes 3, so it becomes the day. So, by creating a state table like this, we need to figure out what input to give for the next state after the current state.

So, the current state is 0, and in order to become state 0 in the next state, what ability do you need? No change, 0, 0, or 4, because of that, it will be 0 or like this. Then, what are these two conditions? The first one must be No change, and the second can be 0, 80, or 1. It doesn't matter. When it comes here, it becomes No change, and when it comes here, it becomes 3, so it becomes 0 ultimately. So, it's the same here. Therefore, in the front, it's dmx, so when you enter sl, it will be fine. Even if you enter 0, the next value will be 0, and if you enter 0, the next value will also be 0. This is the same here. So, you look at the current state and the next state as they are, and you need to find out what input is needed for the current state to become the next state. When it goes from state 0 to 1, in the case of state 1, there is no component, so it becomes an entity that must create state 1.

Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss Ss So the result becomes the current state. If the next state of this lighthouse is to come out, it needs to be reset. So it's a disease without a concept. That's why if you want to go this way, no change, missed it. No change, so it's either 0 0 or 3, so it's a pass. It's important whether it's ari or 2. So, there's no correlation between the back and the front. So please give me the axis. This is how it will be. So this is expressed in this table. So this is how it's made. Then let's walk again. If you create a profile here, you see it's state 0. To define the next state, let's make it with sr. Salome, when the characteristic table is just like that, when it becomes qt plus.

No Change, they are here, so when it becomes 3, 1, next, this one doesn't have a 1, let's ask about this, so it's not used. So, in order to use 1 2 that are not used, jk proof love was created. So when it goes from 0 to 0, it will become 0 or No Change. So, when you write here, it becomes 0x like this. Here, this is the 2 times tab. So, it will be like this, so it becomes 1. So, it becomes 1, and it becomes No Change. So, it becomes 1 or changes to Change or No Change, and this is the error. And adding compensation here, it becomes x 0 because it's 0 here. This is how the second case is, so write it like this. It doesn't mean this here. Enter x here like this, so it will be like this. Right? The average here, like this, Qt plus like this, and put 9 for input here. Then, in the state of J Camp Duplo, there are many cases.

In JK queue with Jake, the feeling of T plus 100 10 is just talking about what's needed in the queue right now. This is the main focus, so when it's 00, the current skill is the same. So, when QT plus 1 is entered, it goes into the queue, causing damage. The Miss A's story is in the SR position, so she misses. So it becomes 0. The skill is high, so it becomes 0. Then, the lost JK NOS R SR is gone. The video complains to QT. If QT is 1, when JK is 1 in the idle state, 0 comes out. And if 1 is entered in the idle state when it's 0, it becomes 1. So, with this, we protect this, and we get the table here. So, to go from 0 to 0, there must be no change, it's a reset. So, no change or reset, right? So, the front is 0, the back doesn't matter. If it goes from nature to work, if it goes from dealer to work, subtract 3 or 3, so it's 10.

In the case of the complainant 4, something behind cannot be x el, right? So, if you switch to English, when you hang up with one call, it will reset or become compute 1. Therefore, backs, well, that's why unusual 5 change or this will happen, right? Use 3 knives and take care together. Yes, that's how it is. So, write a letter like this, like this 9. If you do it like this, it will be fine. You should do it the same way. In the same way, if you want to output in English while in the present tense, then your head will become like this 0. I want to enter 1 in the current English. How to jump, for example, d flip-flop makes the same result as input, right? Because it creates the same output as input, if I want to output 0, it will be in English. Specify what you want to output as 1. T flip-flop gives a signal in English, but it doesn't in English, so it's not a point. So, it's a hero. Well, it's in the back and forth for sale, like this, for example, 2 lighthouse content.

What's so long like this? It won't work like this. Yes, that's right. Toggles are the ones that flip things over. Please flip the back. Oh, there was no tightness here. The 25 petri dish is gone. Yes, then you must have understood the table here by now. But you need practice like this. The long table doesn't come into focus. Because it doesn't come into focus, you need to practice a lot with the table here. Only then you can quickly catch and understand things here. Yes, I mentioned it. How to design a circuit when the expressions here become Sasha. It describes the movement. The movement is like this. Therefore, draw a status table and you can shrink the status table or confirm things like this and set it as a clip flow. Then you can turn on and off each input and output.

And assign it. With this, you write down the state in the * warehouse here. By doing this, each guy finds food. So, if you look at it like this, you can see that. So here, once to the couple, there can be an input, and there are no output variables, and the state changes. Oh, the one in front of me is the input, and I said the output is 5. So, the output. In this case, now, a flip-flop can only store one bit. You should remember that a flip-flop can only store one bit. Since it can only store one bit, it needs two bits for this. If you use JK in your head, you need two of them. You need two, but without using JK, let's make each one into a view. So, if we do that, the state of AB is 000, which is 0001. But if we don't have it, 0001, 1101, 1, 1, 0, 1, 1, there are actually only four possibilities. But the problem is, there are input variables here.

When writing the input number, if 0 is entered when it should be 0 0, and 0 is entered when it should be 0 1, right? So, when writing this, if it is written like that, there are some errors. So, we include x here and use this to mark it. When the next command is 0 0, 0 0, or 0 1, when it faces 0 1, and when it becomes a hero, according to the fate of 00 and 1, when responding, it is inalienable, and in the end, it is the same as writing from 0 to 7 in a 3-digit binary system. So, we put ab here, which means 1 here, so it becomes like this. In the current state, the next state will be like this. So, when 00 1 is entered, it becomes 0 1, and when 0 1 is entered, it becomes 0 1. The reason is that it is a reason. When it is entered here, it goes to the input as an element, and when 0 is entered here, it becomes a hero when the name is given. When 0 is entered, it becomes a history, and when the input is entered, it becomes a hero as it is. When it is 1 0, if it is 0, it remains the same.

If it's already 1 to 1, then he will give you 1 1 to 0, and if you remove 1 2, he will tell you to open it. If it's 1 to 1, do you go to the area? Right, that's it. Up to here, it's a four times table. Next, now if you apply a different table here, like this, J-K becomes 2. Now, the number in front is adjacent to the back 2 like this, you can write it like this. Then, this is A, QT, and T plus 1, right? Here, from 2 to 3, 5, when you go to English, it becomes 16R from the next, right? But, you need a pencil, right? So, you put T after T in the queue, like this, and when you input J-K at this time, how should you do it so that it becomes 00 year L? Like this, it becomes 5, change, and at the time of the reset, it can be 2 with resistance 2. So, it becomes 0 x, right? If you go from 0 to 1, it will be 1, right? In the case of 3 times, there will be one, and there will be cases where it flips because of the occurrence of 0.

So, it becomes 1x. So, in this way, there is a weight loss reset to 01 and a compression watch, right? So, this one becomes x in x length. Then, in this way, when it's 1, there is no change, and when it's 0, there is. So, it becomes the king of x. They are given to each other, so they are lacking. When you just look at this table here, it's a bit difficult to memorize when it's 0. So, when you take the test, do you need this table? Just draw a star next to it, so it's easy to see and use. Like this, from a0 to 0, since it's 0x, it becomes 0x here, since it's 1x. From 0 to 0, it becomes 0x, so it's like this. Then, in this way, is x dominant in this situation? Since they use sex chromosomes, it's x. So, in this way, when it's 0, it becomes x, 1 like this. Alright, then our J&J kb is the same, from 0 to 0, from 00 to 11, it's a sign. So, from the wall to the nutrition, so because of 1, 0.

By doing this, you can solve the problem like this, and why do you need this knife? It costs 500 won, so it's confusing to make it. Enter the variables organically, abx, so the higher place doesn't come out on the right side. Just use a, b, x. Then it will be 00. Uh, raise 1 0 o x x x x 4. Originally, x x x x is the maximum, but since it's all turned on now, it's just written like this. This way, it will be like this. 0 0 0 1 1 0, so this is it. So, write it like jan bx f. Ah, if you look at our cave ka and see the big a of j, and try to get the blood, you'll know what input to put in for me, right? By doing that, when you try to draw a picture, you should capture the output like this from jk to a, jk to bp. That's right. Make it like blog ab Kim Young-hee. What's output is there. So, if you work on this well, it seems like it will be good.

Since there is an input 'ex,' not 'xo,' in cases like this, what is the meaning of 'x-way' and 'the suggestion of &' from 'b'? Since it came from 'b,' it is like this, right? If you draw it now, you can see the current state like this. So, with this state, you can barely obtain things like this. When the current state is not 4x, the next choice is 0, then it becomes 0. If it is xl, it becomes like this, with this kind of feeling. It becomes a black knight of the heart. When it becomes xena, it becomes a butterfly, and the input is one. So when it becomes output, it gives 0. So, this is the case. Like this, you can solve everything. You can solve everything well. In this study, there are practice problems related to creating counters. If you look at them together, it would be helpful. There are also things for all of you. If you misunderstand the state like this for the test, it will never come out on the test, so it doesn't have much significance. See, you can do it like this. Look, it's necessary to have the world of flip-flops in 000.

It's imperative. 00, Aeri. Gyeom-yeong, Yiyeongdae, Goyeong. It's being used. The representative for the 2nd day is also this. So, 0, 2, 0. It becomes Yeong-i, and then Il-i. Lift it like this, press it down, and check the stone carefully. And then, it became Yang-i. This state allocation is meaningless. Remember, memory cells. A memory cell is one flip-flop, so you need three flip-flops for three bits. 50 feet of flute is needed. Then, the spare flip-flop is just one. After the 5th bit, we move on. We will move on to the natural things. In English classes, fortunately, we will omit the sending. So if you upload it, if there are any problems, then here, here, the number of pages won't match, right? The pages won't match. But even if it doesn't match, the output amount will be a bit better, right? So, in case of overflow, use JK. Look carefully at 5. If the number of flip-flops is 5, and the number of states is 5, then you need 3 flips.

There are five different states using Flu. So, to children, what impact does each of the five states have on their English pronunciation? So, for example, it's like this. There are five in total. So, if you look at it broadly, you can represent it as 25 different combinations. Therefore, you need three, three, or three Flus, but you don't use three of the states. I don't know why you only use three. It's okay to reject four. If you look at it now, what state is it? Our next example is 00 Anonymous x0. So, the next state is when the clock is inserted in the flip-flop. When my x12 enters the state, it becomes sick. 014x0 is going to come again. Like this, you meet as shown here, so any random 0x0 prediction has become 01 from ox0, so it continues like this, and this kind of look is expressed here.

I will check it again. It's from 0 to fuel-efficient. There's no change, or it's 0 0, or it's reset, or it's signed by Lee, so give it to sl. Ren's place, so it becomes 4. In the case of becoming 1, you can complain about the complaint, or it's 1 day, or it's 3 times. In this case, you can get 4. Next, with the ones that are found, here, we had a super vertical report. You're logically explaining one by one. It's drawn as a list in France, so when you draw it like this, it's over 100,000,000 1,000,000,000 1,000,000,000. This is the top tray, right? No, it's like this. You copy it like this, so it's fun like this. So you can find it. So if you draw it like a snake, that's how it comes out. Counting various things, you should do five. If you actually do it, it will be as we want.

It will come out. The formality is a bit awkward. If you try, if a is x at a, x is 0, then a, the next output, can be either 0 or 0 again. You used three SR flip-flops, but you need the state as well. It's 000. If the address is missing, do you combine the messages? Yes, it's possible. For example, can't you make a complement frame? Yes, try it. Within a few heroes, it can become 0 from 000 or 0245. So, as I mentioned, analyze the x in a general way. From 00 to 00 to 1, it can be like this. Depending on x, it should be like this when using 4. This is how it should be in this set. This variable is to draw a Karnaugh map, just draw inspiration and minimize it. I can do it like this. It's difficult. Since I've done a lot of Karnaugh maps.

Draw all these like this. When you draw, pay attention to throwing away these days when you circuit these kinds of days. This is the left, the left, this is the lunar calendar. The left is the output. So, you should match the input and output properly and draw it. There are A, B, C gates. The input is here, and the output is here. Then, how does the input work? It's B and C, and you're going to add X here. So, X goes in here, and you do the NOT operation, so for now, you put X1 here. Next, compared to BC, what's the difference? Compared to BC, it's like this. So, it's like this, so it's 4. So, you go straight here, and it doesn't work for OQ. Oh, no, let's go back. Yes, that's right. Now, here is X. Here is the line, the line, here is the bias, zero. With this improvement, you can do it. Please do it. You had to rest for 3. Oh, it's warm. It means not in use. For those not in use, how will you set the value?

Unused state values can be handled by hot processing. If the default state is set as the initial state, it may not function properly. You need to initialize the window state for the usage state. If you look closely, it's 000x0001. When you input a state like this, it can be in a state where these values are not easily visible. Six of these came out like this. When you go into the Alex script, you should go to skill 14, but only this much came out. When you do this, the unused state is LED 3.5. When you try to use it, should I give you unused or similar ones to use? One, four, five, five, the minister using it. So, if you want to use this, you can feel refreshed. This is phone care. In reality, when we boil it, we should add more X leaders like this. Then we need to use it like this, right?

Like this, and then input xa, then l, and then draw it like this, and you should be able to draw more. So, now, here, cx, you write it like this. By drawing like this, the x is in front in the drawing, right? Also, the path of s is more convenient like this, and it is easier to handle the panel like this. When you draw it like this, it's two of these. Drawing like this is a much faster way to get it. However, if you put the logic formula like this, it's a bit difficult to get it because there are many impacts from xab, 00000001. Imagine that there are many impacts like this. But now, if you write the formula like this, then it asks for the value of abe, kway, and av like this, and what is x? But moreover, x is at the back. So, what happens is when it's 0000, then it's a digital gate.

In the case of viewing 0610, when it's 00101, the requirement is now the fare. So, if the variables change places like this, it could be much more complicated to calculate. Or you can just stay like this, draw it like this, and draw it like this, then with a picture like this, a v cx, like this, if the result here is the same, it's useless to write it like this because it's shown here now. The output here is xabc. At this time, the output is abc x1, not output. Do you understand? So, slightly seriously, the results can be handled differently. So, in this case, combine ab and bc to make it x. X is needed here, abx, ok, and so on. Like this, it won't be a problem even if you draw it like this. Now, there are two unused states, first, change to the 0 area. Then the requirement comes up because when x of 000 is 0, when y is 0, it's all 0, and when the mill is reached, like this.

There are four areas. The command is filled with parts. Command 0 1 0 0 0 2 0 should be cleared. It should be cleared to relieve headaches. 0 0 1 0 0 0 1 It's too much. If you take care of everything for Mr. Urae, it will be fine. So, if you do that, it's like this. That's what it means. Please specify. Just look at the natural state and draw it. If you look at it, you will see. With this, 3 bats and 2 binary counters, now you are using alcohol, so it's called a binary counter. Now that it's there, then from 000, you do this, and then this, and like this, this is how it's going to be. In the area of how to do it, in the field command 0 0 1 0 0 1 times are all valid. This way, the words change like this, not like the East, but like this. When the founder changes, what should we do? Towards the dragon here, decorating with 0, you should do it greatly like this, and each one's jk value will be set. With this table, towards the jks, and then jk.

When you solve it like this, this kind of funny expression comes out. Give three variations of funds, so he puts the solid state of the variable world on the left and right like this, and it becomes a PC. For example, if you write it as it is, it will be a bundle of 4 for 0 performances in 1 FR. Because you will see BC. So BC came out, PC came out, and the rest can be solved in the same way, it's not difficult. The important thing is to read the problem well and it's important to find the state. Finding the state means finding the states, finding the states means understanding the state. I don't know, ABC is 0 0 0 to 1, so by what input, how will this be affected? So you can set the state to 9. If you solve it up to here, it seems to be understood completely as before. What did I become? Whatever I become, I win, so now you can solve it. If you have this table, thank you. This is the design of a 5L2 counter. With this picture, you can do it like that.

Here, write down all the possible outcomes that can appear when abc appears like this, when the clock comes out every time, how does it come out? So if you look at it, jumping once every two clocks is the point, right? So, like I'm outputting like my day, when I assume and jump through that, it becomes a profit of output, right? Then, what was initially 00, when c becomes how much, like this, right? So, it becomes 00 when the clock jumps once, and then here, 1 and 2 will go in, right? When it's 1, it goes in one by one above, and then when the cream bread comes out again, since it continues to go in one by one here, it will go to the back, right? It will be interpreted in English as well, and here, since it was a point, it will be 1 nude point, right? That's right. So, next, when the value of shi becomes 0, it became 8 again, and when it jumps to the classic room, since it's in front of me, it should be flipped 0 1 0 1 every time, talking about a loop, and keep an eye on the church.

The clock has ticked in response to grabbing Eung, so this has been inputted as 0000. Since there's no change, that's what it means. If we turn the paper to the completely opposite state from here, can we say that it couldn't be done here either? When the clock jumps, and the next state becomes Eung, there are two beings with a length of zero, which becomes a two. When the input is made in that state, if the clock jumps, these things here will be inputted as 1. So, it goes up. Yes, it becomes a direction. Still, when you color it, the planning will be greatly improved. Yes, it can be like this, like this. Here, let's make one related to list 3. This counter, how the numbers are represented by this counter, is a new one. Then, 0, 1, 2, 3, heroes 123 can be enough, or 0, 1, 2, 3, 4, 5, queens 345 can be like this. Depending on what you put in the list, it can change. So, you can do it like this. Oh, I'm getting sleepy, so I can't say exactly.

Speaking is not wrong, but oh, it's a bit off track. D flip-flop, right now here is a T flip-flop. Earlier, I talked about putting a 2k resistor like this, just putting it in like this. If you put this in, it keeps flipping the state continuously. If you connect it to the J and K of the JK flip-flop, it keeps flipping the previous state. The result was 010001. So, it can be solved by people. For example, we are JK, but in reality, it was a T flip-flop. When using English, it was also mentioned here. There are two D flip-flops. Again, it became 0. And then, according to this, work was done in this state. For example, at 6, it goes like this. Oh, yes, that's right. Look at this and then try drawing a day like this. It's the same as creating a 4. But this is.

If you look inside the new, what else is there? Recently, there are good signals here. Booker is here. You can try this. It's okay to do it like this. Since there is no input, for 1,000 people at 000, in terms of 1,000, the calorie is adjusted like this, and it changes like this. Assuming that everything changes like this, turn it on, and it doesn't work. If it's not counted, just handle it all straightforwardly. Using the equation of state with the use of fluoro fluoro at state 2, here, ab x, so a b e x, by putting in the command 0 0 1 0 1 0 0 1 1, you can turn it like this. So, if you logically figure it out, just do it with a logical formula. So, like this, why do it like this? If you just look at it, that's fine. Dip Dupler Ben.

It's 0 but 1 came out. This is input data, so it comes out as entered. This one is output data. Regardless of the previous state, it just comes out as you put it in. So, if you look closely, you can fix the one you put in. It's almost like a puzzle. For example, it doesn't go up to 73 seconds. This is how it is. Just looking at the computer itself, there doesn't seem to be a big issue. I cut it into 5 pieces, but if you look at it as 0, it would be better for you to see, so I won't do it. I will explain the design using the decoder pre-flow. The decoder design scale code is raised to 5, and the deck is called a codec. When you look at the English codec, it's not responsible for sound because there's no sound codec. It comes out like this. This is the code, and the T code is where the code is. So, we compress the video and sound and save it. If we just do it, it's too big, so we compress it and save it, then when we play the movie, it unfolds the compression.

It's about T-codes, which are called codecs because they supply high-pressure air. So, the decoders, they talk about blue air, blue air, which means the funding increases, right? So, the D-code has three inputs and produces eight outputs. So, with three inputs, it can generate output up to eight, right? If you have four inputs, you can make up to six outputs. So, the decoder gives two to the power of N minimum outputs for N input variables. Please do one T-code for the company. That's right. By doing this, then the X value goes from 0 to 1 transparently and approaches 0, creating a smooth transition towards 0 and then reaching a maximum of 9, right? Then you should solve this difficult T-code problem. It seems like that's the case. Then, let's consider the inputs. Oh, this seems quite reasonable. Just 5.

What comes out big is to watch 4 and then use the flip-flop of that person to make a street code counter using the decker. Then you just need to continue with the code, right? So, if you keep 1 bit of $100,000 in the designated area, it will change. It changes what is required, and what is required changes. So, you need to keep it nicely and create a crayon code. That's how you can make it. Well, it's not just halfway done. It's not just a longing. Just by looking at the picture, it doesn't seem like it's just halfway done. If there are suspicions, there may be some trading. It hasn't come out once yet. Even if you think about it, it's 4. This was made with a benefit, but it doesn't seem like it will be very helpful to you. But you should try solving the counter count problem. The most difficult thing is the vending machine problem that came out. A long time ago, yes. For those who like to solve hard problems, they must have seen it very difficult.

It's a bit difficult to use, just like photos. Anyways, after the vending machine issue, there's another issue with the screen. In the end, everything goes back to the initial state and the subsequent state. The flip-flop, flip-flop, and flip-flop of each one. So, if you make it weak in terms of input ability for each of them, like 1, 2, 3, you should be able to enjoy playing the flute in an interesting way. You should practice a lot to quickly grasp what the input of the flip-flop is, so you need to observe it carefully. Alright, it's 3:13. Have a good day in 2013, and thank you. Please like and subscribe. Do you see it? For June 25th, also for the 2:00 session, click on the bottom right for the application. If there are better materials, they will appear again. Oh, this digital circuit is...

Let's do it until the end once, and then if you need any lectures, please request what you need. I will try to upload more lectures. Please do your best!
