ABSTRACT:
Circuitry for detecting the spectral distribution of a signal that is phase indicative of a digital logic level and providing feedback signals for use in adjusting the signal amplitude of the spectrum to have a substantially zero slope over the relevant frequency bandwith. The correction is obtained by applying voltages to variable impedance pin diodes forming part of a tuned filter circuit.
