I've been try to design a second order all pass filter but I'm having a lot of trouble finding a source that actually explains how to calculate the right component values. I especially am looking for a formula or equation which I can use to modify Q with so that I can play around with my circuit till I get the result I want. Does anybody know where to find a circuit schematic that is also accompanied by some equations and formulas?
I greatly appreciate any help I can get.
