Abstract

PURPOSE: To secure an accurae deletion of the disturbing signal for the residual side band wave modulation system of TV or the like by detecting the disturbing signals via the reference signal or its corresponding signal during one horizontal period in which only the burst signal within the vertical flyback period exists.
CONSTITUTION: The signal of terminal 7 from which the disturbing signal of the luminance signal is deleted via subtraction circuit 6 is applied to subtraction circuit 12. And the output of circuit 12 is supplied to output terminal 13 as well as to the input sides of delay circuits H1∼HK corresponding to the sampling period of 4 times the chrominance subcarrier frequency through filter 14 which corresponds to the chrominance subcarrier frequency. Furthermore, the output of filter 14 is applied to disturbing signal detector circuit 16 to detect the disturbing signal, and the output is applied to control circuil 18 controlling the gain of level adjusting circuits I1∼IK via differential circuit 17. And circuits I1∼IK are controlled in case the distortion exists during one horizontal period of only the burst signal within the flyback period. Then the signals corresponding to the signals sent from filter 14 are controlled to delete the disturbing signals of the chrominance signals through subtraction circuit 13.
