FIELD: radio engineering; broadband-signal communication systems. SUBSTANCE: noise suppression device that depends for its operation on noise cancellation has three band filters 1, 2, 6, two adders 3, 10, minimum selection unit 12, two subtracters 5, 11, two rectifiers 4, 7, cosine function generator 8, and divider 9. EFFECT: enhanced reliability of noise suppression compared with prior art. 1 cl, 5 dwg |
