Abstract
A superheterodyne receiver is described for demodulating signals containing both amplitude and angle modulation components. An intermediate frequency signal is produced which is simultaneously amplitude detected as well as angle demodulated. Detector means are provided for detecting the occurrence of high negative amplitude modulation peaks of the broadcast signal. During high negative amplitude modulation peaks, the angle demodulator output is held at a fixed level until the amplitude of an input signal is restored to a predetermined minimum level.
