Tunable Active RС All Pass Filter

An implementation scheme for active RC all pass filter of the second order with independent frequency and Q-factor tuning is considered. The frequency of the all pass filter is rebuilt nine times with a single potentiometer with a constant phase-frequency characteristics slope and unitary value of the transmission coefficient in the operating frequency range.
