FIELD: radio engineering; receiving devices. SUBSTANCE: newly introduced in device are series-connected first multiplier, first low-frequency filter, and second multiplier, as well as amplitude detector, switch, third multiplier, second low- frequency filter, and phase shifter which makes it possible to shape estimate of maximum-level narrow- band noise whose frequency, amplitude, and phase are automatically tuned to those of respective narrow-band noise in input mixture thereby raising degree of narrowband noise suppression including cases when its parameters are changed. EFFECT: enhanced degree of narrow-band noise suppression. 2 dwg
