So let us continue and see how the law is working step by step, I have added in order to stabilize
here so that we can follow together, if you have forgotten what those are the truth table looks like.
So remember, Lenore is giving us a one only when and beyond zero.
Otherwise, it's always giving us zeros at the output.
So.
We are going to start with initialised state.
Let's assume that the initial state is where Q is zero zero and always zero.
Fair enough.
Now, let us see, will this circuit bounce or not?
The zero right here will jump back.
To this gate right here.
Now, here we have zero and zero going to this no gate now, zero and zero, what does it give?
It will give us one, right.
So we will see one.
Stuart.
And that what is we are expecting when we have a zero here, we will see a one here and this is the
initial state.
OK, great.
So let us continue.
Now, see this one here, it is also connected back as a feedback to this north gateway to you.
So we have one right here right now.
Now, we have a zero here and the one here that are going to this.
Nogi, what will it give us?
Well, it will give us a zero, right?
Because as you can see, zero and one give us a zero.
And now the zero will bounce back here.
It's still zero.
It will give us one.
It will get bounced back to here and it will give a zero.
And this will go infinitely.
And as we can see, we are retaining the zero right here and it's not changing at all.
So this is for the initial state and that's great.
Now, let us check the state now assume that this has turned from zero to one, right.
We're just switching gears now.
We have already zero retained here, right.
So one zero.
What will give us.
We have one zero.
It will give us zero.
So now we have zero.
Excuse that the zero with the propagate back all the way here.
Right, it propagated here.
Now I have zero and zero going to this no gate zero zero will give us one at the output.
So.
Q Now is one.
That's great.
We have set Q to one, but let's continue.
This one right here will propagate back all the way here.
So I have one here and one here, one on one.
What will it give us.
It will give us zero.
That's great.
Now, let us check the reset.
So if my set is zero and my reset is zero rating, well, we have one zero coming here, one zero,
which will give us a zero.
So this will turn into zero.
Now, this will propagate back all the way here right now.
Zero and zero right here.
What will give us a one?
So we are going to see one at Kohat, right?
So this is a reset, the one that was here is now a zero, and you had is the one.
That's correct.
This is our main output.
This is what we want to reset.
Now, this one.
Can propagate back here, so one and we have one here, what will give us a zero?
So the zero is retained here and this will continue infinitely.
I want you to follow this on your own and try to see on your own how a nasal latch works.
I have already explained it, but I want you to go through it one more time by yourself so that you
can get a good grasp of the concept.
Now, let us check.
Not allowed state.
Now remember, you should be the opposite of your hat all the time.
And one when we put one on and one on.
As we're going to get unpredicted behavior, we could be stuck at one stage, we could be bouncing.
It really depends.
So let us see in this case what we will be having.
So right now we have put one at risk and one set.
So one and zero here is going to give me a zero zero to propagate all the way here and now.
I have one and zero right here at the same time.
Right now, this one and zero will give me a zero here.
And this zero right here is going to jump this way.
Well, Nancy, I will give me a zero.
And he'll be having a zero, this means that you is a zero and that's a contradiction.
You had.
Not have the same value.
So this is why and so let's not have RNC and with a value one at the same time.
Now we will continue later to see how we can prevent this issue.
