Summary:FIELD: radio engineering; data reception from communication channels. SUBSTANCE: device has mixer 1, intermediate-frequency amplifier 2, correlator 3, demodulator 4, data recipient 5, heterodyne 6, standard signal generator 7, and synchronizer 8. In presence of interference in such device noise immunity of signal received abruptly reduces; that is why functional converter 9 executing f(x) = 1/(1 - x) operation has been introduced. EFFECT: enhanced noise immunity of signal received. 1 cl, 5 dwg
