I'm in need of a bit of help regarding filters. Specifically, filters with inductors.
I know how RC filters work, and I understand reactance, and that a resonant frequency is formed when capacitive reactance is equal to inductive reactance.
Some questions:
- what is the equation for a LC filter?
- what is the equation for a LRC filter? Is it RC's f=1/2piRC?
- is it possible for the resonant frequency to be different to the cut-off frequency?
- is it possible to increase the amount of resonance in a circuit? some sort of feedback, perhaps?
thanks.
