Hello
I want to design a butterworth band pass filter. The frequency passband is between 18KHz to 22KHz. I would want to use RC 4 pole (4th order) filter using LM324.
The filter design will be used to allow the audio asignals within this range while the remaining part will not be.
Sallan Key 3 pole should also be feasible.
I am nor sure about the appropriate design to use. Kindly suggest if there are any feasible options. Any notes for the calculation of the same will be very helpful.
