Abstract

PURPOSE: To secure an automatic correction for the time axis to the time fluctuation of the signal by securing the control for the delay time of the delay circuit through the phase comparator, the low pass filter and the voltage control oscillator.
CONSTITUTION: The time axis fluctuation of the signal, if any, is detected by phase comparator 23 to be then delivered in accordance with the phase shift of the comparison signals. This detection output is applied to the control end of voltage control oscillator 18 via low pass filter 24. As a result, the control is given to the phase of the transfer clock pulse of 1H-delay unit 17 which gives the 1-horizontal line time delay to the signal information, thus controlling the delay phase. As a result, the steady time axis can always be maintained to ensure the steady isolation for the signals.
