Hey guys,
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?
