Filed: 1978-04-07
Abstract: PURPOSE:To realize a general carrier digital tranamission system by preventing a phase synchronous circuit from having an undesirable phase lead-in stabilization point even when a modulated wave is a continous wave. CONSTITUTION:To the input of the phase synchronous circuit, a composite PSK/ PSK-modulated signal is supplied which is obtained by two-phase-PSK-modulating a signal, two-phase-PSK-modulated by a main data signal, by a sub-data signal. This input signal is detected by taking the output signal of voltage control oscillator 20 as a reference carrier.
