FIELD: radio engineering. SUBSTANCE: device has N frequency channels 1. . . 1. N, adder 2 and N units for noise detection 3. . . 3. N. Each frequency channel has band-pass filter 4 and N circuits 5. . 5. N. Each circuit has input phase shifter 6, attenuator 7, switch 8 and subtraction unit 9. Each unit for noise detection has input detector 10 and output threshold gate 11. Device provides decreased distortions of leading edge of signal radio pulse during suppression of arbitrary number of narrow-band noises because compensating radio pulse is generated with delay to input radio pulse. EFFECT: increased functional capabilities. 3 dwg
