The Research of a Noise Stability of Reception is Frequency of the Modulated Signals by the Reception Device with Exception Threshold and Pulses of Noise

The outcomes of an experimental research technically of realized device of a reception of FM - signals having an increased noise immunity in a comparison with the standard discriminator, are obtained. The comparative evaluation of experimental threshold curves with the theoretically designed relations is conducted. Is shown, that the application of the given device shifts a threshold point to the left on 1,5 дБ on a comparison with the standard discriminator, a advantage in the relation the signal / noise on an output of the demodulator makes from 2 дБ up to 6 дБ depending on an index of frequency modulation and relations a signal /noise on an input of the receiver of FM - signals smaller 5 дБ.
