ABSTRACT Disclosed is an amplitude equalizer having little or no delay distortion and requiring only a small sized circuit network. In one embodiment signals having an amplitude distortion within a predetermined frequency band feed a first branching circuit for branching the signals into two. One branch feeds a first delay circuit having a predetermined delay time within the frequency band. A second branching clrcuit branches the output af the first delay circuit into two, one of which is connected to a second delay circuit having a delay time equal to the first delay circuit. A first combiner combines the other output of the first branching circuit and the second delay circuit and feeds a circuit for varying amplitude and/or polarity. The other output of this last circuit is combined with the other output of the second branching circuit to provide equalized signals.
