Abstract

An improved FM receiver is disclosed incorporating improved oscillating limiter circuitry having an electrically tunable bandpass filter and variable attenuator in regenerative feedback relationship around the limiter. The electrically tunable bandpass filter is responsive to DC components and high frequency noise components of the demodulated video baseband signal. The variable attenuator is responsive to the carrier-to-noise ratio of the received FM signal whereby the amount of regenerative feedback around the limiter will vary inversely proportional to charges in the carrier-to-noise ratio.
