To start: I believe this is a low pass filter gain equivalent circuit, with Capacitor in feedback with two resistors.

To find the resistors I wasnt really sure but I found something in my textbook Req = 1/C*f, so could I use the two separate capacitors and frequency switches to calculate the equivalent resistances?

So the low frequency gain would be A = -R2/R1, where R2 and R1 would be the equivalent resistances based on the capacitors and frequency.

And fo = 1/2*pi*R2*C1 ??

Could someone please check this logic over and get back to me. My assignment is due SOON!
