ABSTRACT:
Circuitry is disclosed for detecting signal amplitudes of a signal which is phase indicative of a digital logic level and providing a feedback signal for use in amplitude adjusting the signal to have a substantially zero slope over the relevant frequency bandwidth and zero notch in the middle of the band. The compensation is obtained by applying a voltage to variable impedance pin diodes which form part of a reactive load circuit.
