Effect Of Phase Unbalance In Product ModulatorPaper presents theoretical study of effect of phase unbalance in product modulator of phase-modulation transmitter in deep-space telemetry system upon performance of system. Mathematical model of product modulator used to derive equations for relative strengths of desired suppressed-carrier component and undesired residual-carrier component of transmitted signal. Also addresses effects of unsuppressed-carrier component on carrier-tracking phase-locked loop and bit detector in receiver.
