Abstract

PURPOSE: To avoid the large fluctuation of the frequency for the reproduced carrier wave at the non-signal time by providing an oscillator featuring the frequency approximate to the frquency of the reception signal and then applying the output of the oscillator to the input of the phase detector in case no input signal exists.
CONSTITUTION: Output (b) emerges at T of signal detector circuit D only for the time during which input signal (a) exists, and switch circuit Sw opens only for this period to intermit (d) the output (c) of oscillator OSC. As a result, the output (e) of adder circuit ADD which uses signal (a) and output (d) as the input is supplied to phase detector PD. The signal wave featuring the frequency approximate to the input signal frequency is applied to the input of PD from OSC even at the non-signal time [signal (a) is 0]. As a result, the large fluctuation never occurs for the reproduced carrier frequency resulting from the lost of the PD's balance
