Abstract

PURPOSE: To prevent the error of data regeneration by leading the phase of a reception-side synchronizing signal into that of a clock line pulse.
CONSTITUTION: Color subcarrier frequency signal A is multiplied by eight to obtain signal B, which is also multiplied by 1/10 to obtain signal C. Then, signals B and C are both supplied to phase shifter circuit 3. Parallel outputs D-1 to D-10 of phase shifter circuit 3 are supplied to selector 7, in parallel, according to the lead in phase (or lag). Corresponding to address output 10 from address counter 9, selector 7 extracts one of outputs D-1 to D-10 as output E. Output E is supplied to phase inverter circuit 12 and extracted as phase-coupling output signal H. Output signal H is applied to phase comparator 14, where it is phase-compared with input signal (clock line signal) I, and address counter 9 is driven depending upon error signal J, so that the phase of signal H will be led into that of signal I.
