Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

I recently had a quiz on

Circuit is attached in photo below.

T(s) = (A)(s/s+20)*(s/s+200)

**All values of R in the circuit attached are 2000 ohms.

and C1>C2

a. find the mid-band gain A.

I do not know how to start this question... Can anyone give me an idea of where to start.

b. find values of C1 and C2

For this problem I got a little confused when applying OCTC and SCTC

Firstly, would 200 be my upper corner frequency? If so,

200 = 1/(Rth*Ci)

Where Rth= thevenin resistance, and Ci = the capacitor we wish to analyze the effect of the pole.

So basically, I open circuit C2 and I short circuit C1 and find the thevenin resistance from C1.

Can anyone confirm if this is correct?
