Hi all, I have a Wien bridge Oscillator which I measured the output frequency on the oscilloscope and is about 1KHz.
Now, I am trying to calculate it theoretically, but I can't obtain the same result. I am sure that I am calculating it in the wrong way.
I know the formula is 1/(2πRC), but exactly, which resistance I have to consider in the circuit?
R3 or R4? Or the Req between them? I have the same doubt for the capacitance.
Off course I attached an image of the circuit.
Thank you for your help.
Regards,
