I've transcribed here, so everything that's in that very aqua -ish color is transcribed.

And we are asked to find vo for each one of the networks of a and b.
00:13
So the voltage applied at the negative terminal can be expressed as vi plus 4.
00:22
The diode turns on, wait, when that value, when negative.
00:46
So we can do v i plus four.
00:50
Okay, the diode will only turn on when v i equals negative 5.
01:07
So my output voltage at that point will equal negative 5 plus 4 equals negative 1 volt.
01:29
And we look and look at that if i want to take a look at my voltage here, if this is 0, and this is let's just make this.
01:47
I can't really do it on that one.
02:04
So let's go from this to this.
02:11
This is zero and negative five, five, ten, 15, 20...
