ABSTRACT:
A variable amplitude delay equalizer network comprising generally a 90.degree. hybrid matrix consisting of toroidal transformer and two capacitors and having an input, an output and two reference ports. A reactive network at the first reference port forms a network which allows input energy to be shifted in phase and returned to the hybrid, thus providing envelope delay correction. An amplitude corrective network at the second port permits adjustment of the amplitude response essentially independent of envelope delay adjustment.
