So we're given the transfer function for this circuit with some unknown constants in it.
00:05
So what i want to do is calculate the transfer function.
00:11
And then what constants will appear.
00:14
Right.
00:14
So i'm going to define two.
00:19
I'm going to do this using mesh current.
00:21
We'll call this one i -1.
00:25
This one is i -1.
00:35
And then i get two equations from the loop law.
00:43
So the next thing i'm going to do is take the laplace transform of these equations.
02:33
And my variables are going to be this.
04:11
When we're calculating transfer function, we know, just because we know i2 is a derivative of capital i2 is a derivative of capital q2.
04:28
So this is where this comes from.
04:31
And then we also need.
06:27
So we get this.
06:36
Equation.
06:37
We also know that vc, so that q2 is cvc.
07:10
So we got it.
09:07
So we can get the transfer function...
