Abstract

FIELD: radio engineering; short-range navigation systems. SUBSTANCE: receiver has logical unit 1 implementing logical function x ∧ (z ∨ y), where x, y, and z are logical signals across its first, second, and third inputs, respectively. Outputs of threshold elements 3, 5 and 10 are connected to inputs of logical unit 1; operation thresholds of first and third threshold elements 5 and 3 are lower than operating threshold of second threshold element 10 by valve equal to sensitivity of first and second processing channels terminating in amplitude detector 11 and amplifier 9, respectively. Sensitivity of second channel is lower than that of first channel by value equal to difference in sensitivities of first and second channels. Signal will arrive at output of logical unit only in case of main-channel signal reception as main-channel signal is more powerful than spurious-channel one. EFFECT: improved spurious-channel selectivity. 2 dwg
