I will analyse filters as a sub-set of the circuit. I choose filter because it is a core component of the audio equipment I have designed since it is responsible for ‘generating’ the high and low frequency signals that are fed to the tweeter and woofer respectively.
Filters
Unlike resistors, the opposition (or reactance) to current offered by capacitors and inductors vary with frequency. At lower frequencies, the reactance of inductors is low while that of capacitors is high. At high frequencies, the reverse happens and the reactance of inductors is high while that of capacitors is considerably reduced. Thus at very ...
