FIELD: radio engineering; multichannel communication systems. SUBSTANCE: device designed to receive tone signals in multichannel communication systems is provided with newly introduced four integrating sections, subtractor, ratio computing unit, threshold element, and display unit. Estimates of signal power in data band, input signal energy distribution over frequency band, peak factor of signal received, and degree of irregularity of input signal envelope in band filter are used as resolving characteristics. EFFECT: enhanced precision of tone signal discrimination. 1 dwg
