FIELD: radio engineering. SUBSTANCE: frequency demodulator has series-connected intermediate-frequency band filter, limiter, and low-frequency filter, as well as delay line connected between limiter output and other input of multiplier; delay line is, essentially, Gause filter of at least fifth order. EFFECT: reduced power requirement and improved quality of frequency-modulated signal reception. 2 dwg
