Abstract

PURPOSE: To remove the image surface beat interference and the voice bus interference by obtaining the control signal in accordance with the generation condition of the cross talk and thereby controlling the feedback signal for erasing the cross talk.
CONSTITUTION: If the cross talk of the base wave of the positive polarity during the output of the image remains, the output of the correlator 20 is positive and in the square circuit 15 output namely in the feed back signal 23, the base wave component of positive polarity is generated. Accordingly, by the subtracter 17, the base wave cross talk in the output of the image signal is erased by operating the feedback. Then, if the base wave cross talk of the negative polarity is present, similarly negative feed back is operated. The two times wave cross talk component is by a fixed amount and the polarity thereof is fixed, so that the by the correlator 20' and the gain controller 16, the polarity thereof is not changed and simply controlled to remove the cross talk.
