ABSTRACT:
A high frequency circuit is arranged to modify a signal, such as a television broadcast signal, prior to high power amplification so as to compensate for distortions introduced by the amplifier. Separate signal paths give independent adjustment of the differential gain, differential phase and linearity of the signal by altering the characteristics of level dependent detectors.
