FIELD: radio engineering. SUBSTANCE: suppressor has concentrated-noise protective units which function to reject spectrum of interferences affected by narrow-band noise. Rejection of separate frequency components results in signal response across output of matched filter (correlator) with central main spike and many side spikes comparable in amplitude with main spike. Proposed device provides for minimizing distortions of signal response (convolution) across correlator output due to shifting frequencies of signal spectral components which fully eliminates rejection area of spectrum sections, and dispersed sections of spectrum are tightly joined together so that spectrum envelope becomes quasi-smooth and unimodal. EFFECT: improved noise immunity in receiving broad- band signals.
