摘要:
An all-pass system particularly adapted for equalizing group delay distortion in wide band communication systems. Two common emitter stages having adjustable resonant circuits are arranged in parallel to receive a single input and to linearly combine the outputs of the stages. One stage is wide band and the other is frequency selective and the output of the selective stage is twice the amplitude of the wide band stage and phase inversion is provided such that the outputs of the two stages are 180* apart.
