A Method of Lowering the Noiseproofness Threshold of Braodband Frequency Modulation and Phase Modulation Receivers,
Abstract
The patent describes a system for lowering the noiseproof threshold of wideband FM and PM receivers by a relative increase in the carrier level of the signal realized after the preliminary transformation of the wideband signal into narrow band. The transformed narrow band signal feeds into two parallel filters, one of which (narrow band) admits the carrier and weakens the side frequencies and the other (wideband) uniformly weakens the entire spectrum of the narrow band FM or PM signal.
