Abstract

PURPOSE:To obtain a stable synchronizing circuit of high precision by digitizing the operations of a phase comparing circuit and voltage control oscillator. CONSTITUTION:On input signal fi, superposed DC voltage E0 greater than its amplitude is superposed by DC superposing circuit 1 to obtain a unipolar signal, which is applied to A/D converting circuit 2. As for the output of circuit 2, the antilogarithm and complement are alternated by addition-subtraction alternating circuit 3 in every half period of local signal f0 and addition and subtraction are performed by the following integrating circuit 4 in every half period. Input signal fi is integrated according to the expression (theta is the phase difference between signals fi and f0 and (omega) is the frequency of fi). Then, a pulse is generated at the conversion point of signal f0 by differentiating circuit 9 so that the output of circuit 4 will be zero. Then, the contents of circuit 4 are transferred to latch circuit 5 to control pulse rate varying circuit 7 on the bais of the contents, and consequently an input to frequency dividing circuit 8 is adjusted to control the phase of signal f0.
