摘要 |
radio engineering; communication systems using broad-band signals. SUBSTANCE: upon taking decision on synchronizing by useful signal additional check is introduced in device enabling detection of false synchronization by noise. Device has three multipliers, two band filters, two amplitude detectors, resolving unit, search control unit, code generator, two switches, rejection filter, two phase modulators, threshold comparison unit, limiter, and four delay circuits. EFFECT: improved noise immunity. 3 dwg
