REFERENCE WAVE SHAPER FOR COHERENT DETECTION OF RELATIVE 180° PHASE KEYED SIGNALS

摘要

FIELD: radio receiving devices for relative phase-keyed signals. ^ SUBSTANCE: proposed reference wave shaper for coherent detection of 180 deg. relative phase keyed signals has frequency doubling unit, second harmonic filter, phase shifter, power amplifier, parametron, electronic switch, low-pass filter, and phase detector. ^ EFFECT: eliminated phase jump, enhanced noise immunity in signal reception. ^ 1 cl, 1 dwg
