Abstract

PURPOSE: To ensure the accurate regeneration of the carrier along with reduction of the jitter on the screen for the facsimile signal carrier regenerating device by providing the gate which makes pass through the phase error signals only in the first phase matching period and the picture signal flyback time.
CONSTITUTION: Phase comparator 1 compares the phase between facsimile signal S1 of input 5 and regenerated carrier S2. And the error signal is formed according to the phase error. This signal is made to pass through gate circuit 4 only in the first phase matching period and the flyback time under transmission of the picture signal. Control voltage generator 2 generates the control voltage based on the phase error signal and then generates the regenerated carrier through voltage control generator 3. In such constitution, the carrier can be regenerated accurately even in case the facsimile black signal continues long or short. Thus almost no jitter is caused to the picture received.
