Abstract
PURPOSE: To obtain an excellent subcarrier signal with a little jitter by extracting only pulses which correspond to either 1st or 2nd phase of an extracted burst signal and making them phase-synchronize with the burst signal.
CONSTITUTION: Phase comparator circuit 10 discriminates the 1st phase and 2nd phase of an extracted burst signal, and by its output, reset pulse generating circuit 11 generates pulses corresponding to either 1st or 2nd phase. On the other hand, FF8 is set by a horizontal synchronizing signal and reset by a pulse, and gate circuit 9 outputs selectively either burst signal of the 1st or 2nd phase by the output of FF8. Then, oscillation circuit 6 generates subcarrier signals of continuous signals following and synchronizing with the burst signal supplied from the output of circuit 9. Consequently, subcarrier signals can be obtained with a little jitter
