Here, we want to draw a logic circuit with these inputs given the bullying expression.
00:08
What i like to do is let's just start off with the gates that we need to draw, and then we'll put the signals in later.
00:14
So we need to have, first off, abc, so that's going to be an and gate with three inputs, and then we're going to have another and gate with two inputs, and another and gate with two inputs again.
00:25
And these are going to be added together to give me an or gate with three inputs as well.
00:35
That will output to give me l.
00:37
So let's just put here, here, and here.
00:42
And then we have a, b, and c.
00:46
So let's just label these a, b, and c.
00:50
But now we need to input a prime and b prime.
00:53
So let's get an a prime out of this by getting, let's move over across this and go through an inverter.
00:59
So that's a prime.
01:02
And then we need c prime.
01:05
We're going to need a b prime.
01:07
So let's go ahead and get a b prime.
01:10
It comes from here through an inverter...
