(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given: K=17, R1=R2=6,247 Ohm

Calculate the value of C1=C2=C to set the center frequency of the filter to 17.3 kHz.

2. Relevant equations

w0 = 1/[C*sqr(Rth*KR2)] from lecture notes

R1=Rth

3. The attempt at a solution

w0 = 1/[C*sqr(Rth*K*R2)]

C= 1/[w0*sqr(Rth*K*R2)]

C= 1/[2*pi*17.3k*sqr(6247*17*6247)]

C= 3.57e-10 F

The equation above is from a similar circuit that doesn't have R2. I wasn't sure if it still would work. Looking at the circuit above. It seems like R2 does not impact the function of the circuit.

Any help would be appreciated.

Thanks.
