ABSTRACT:
An amplitude equalizer includes a pair of serially connected unit amplitude equalizers, each having complementary delay distortion characteristics to flatten the overall delay distortion characteristic. The unit equalizers include amplifiers or attenuators, delay circuits, and/or phase shifters. The amplitude versus frequency characteristic of the overall equalizer can be varied by controlling one or more of the attenuator/amplifiers and phase shifters. The variation can be controlled by a feedback circuit.
