    Band Pass Filter: Calculate C1=C2 for 17.3 kHz

    V- does not need to be called a variable because the V+ is connected to ground thus V- is a virtual ground too. Right? The KCL equation I got for node V1 is: KCL1: (V1-Vin)/R1 = (Vout - V1)/(1/sC) + V1/(R2 + (1/sC)). For Vout node i got: KCL2: Vout/KR2 + (Vout - V1)/(1/sC) = 0 Are...

    Band Pass Filter: Calculate C1=C2 for 17.3 kHz

    The equation uses K*R2 which is equal to R2 in the similar circuit. No, I don't know how to write KCL equation for opamp circuit with feedback. It's been a very long time since I used it. Can you help me get started?
