ANALOG PHASE-MODULATED SINGLE-SIDEBAND SIGNAL RECEIVER

摘要

FIELD: radio engineering; reception of phase-modulated single-sideband signals. SUBSTANCE: signal is shaped across demodulator output by adding respective portions of signal picked off output of diode-type arctangent transformer, their phase being varied or maintained constant depending on polarity of information signal derivative; this signal is transmitted together with operating sideband. In the process input signal undergoes real-time transforms as demodulator input signal (modulating function) is analog and not digital signal. EFFECT: enhanced speed, reduced cost of services rendered to user. 21 dwg
