Abstract

PURPOSE:To reduce the variance to the elements and thus ensure a steady working, by forming with a digital circuit the equivalent pulse eliminating circuit which is used for the means to obtain the carrier signal in case the color signal receives the frequency conversion. CONSTITUTION:The composite synchronous signal input terminal 21 is connected to the NAND circuit 24. At the same time, the 1st output terminal of the circuit 24 is connected to the 1st input terminal of the NAND circuit 26 via the shift register 25; and the 2nd output terminal of the circuit 24 is connected to the 2nd input terminal of the circuit 26 each. And the 3rd output terminal of the circuit 24 is connected to the 2nd input terminal of the NAND circuit 28. Then the clock pulse input terminal 22 is connected to the clock pulse input terminal CP of the D type F-F circuit FF1 and FF2 each. Accordingly, in such circuit both the reversed signal and the output signal of the output terminal Q of the D type F-F circuit FF7 are applied to the circuit 28, thus obtaining the horizontal synchronous signal in the horizontal period.
