Abstract

PURPOSE:To follow the system with the variance of reception signal quickly, by constituting the line synchronizing signal generating circuit with two frequency dividers at the input and otput sides, and controlling the frequency divider input at the output side according to the variance of the reception signal. CONSTITUTION:In the synchronizing matching system where the reception side is synchronized with the transmission side, the lead or lag signal of phase is output at a phase comparator 13 according to he variance of the reception signal. Further, in electronic switches 18, 14, 5, when the lead signal is output, the transmission of the output of the 1st frequency divider 1 to the 2nd frequency divider 2 is tentatively intermittent and when lag signal is output, the output of the smaller frequency dividing ratio than that preset at the 1st frequency divider 1 is fed to the 2nd frequency divider 2, by means of the switching.
