And this lecture, we're going to compare conventional logic to sequential logic in most of the previous
lecture we were talking about computational components and in general, the conventional components
are logic.
It is like a bunch of logical gait like and or X or X nor.
But they don't have any storying element or there is no feedback from the output of this game to its
input.
So whenever you have a feedback, meaning whenever you connect your output back to your input in some
kind of topology, you will be having some storying elements.
So far we did not have that.
So I conventional logic contains no memory element in order to store data permanently, meaning it has
no feedback between outputs and inputs.
And it's relatively easy to design because all you need to do is just put your logic gates next to each
other and you will have your circuit just as simple as that.
Now, if you're going to talk about sequential, we are going to look at the Bolaji like that where
we have our computational logic, but there is a feedback from the output to some memory element back
to the input and then this input.
It's feeding back the combination of logic.
So we are talking about a closed loop logic right here.
So this is very important.
If you want to start talking about finite state machines or if we want to talk about some circuits that
can have some sequential steps.
If you want your circuit to memorize sequential steps, you need to design using sequential components
so we can store data, you can store states and they require a clock and rig to operate.
And we're going to talk about clocks and regrows later.
And of course, we need a feedback to the output and the input.
So the next lecture will talk more about these concepts.
