Abstract

PURPOSE: To remove the image surface beat interference and voice bus interference by obtaining the control signal in accordance with the generation of the cross talk and thereby controlling the feedback signal for erasing the cross talk.
CONSTITUTION: When the cross talk is generated in the voice FM signal from the image signal in the input signal, the interrelation is generated between input signals of the first multiplier 16. Thus, the signal is produced at the output of the multiplier 16 and the size and the polarity thereof are determined by the condition of the cross talk. This signal is fed to one of the second multiplier 18 as the control signal from LPF 17. The image signal in accordance with this control signal appears at the output and is added to the subtracter 15 as the feed back signal. The feed back signal is subtracted from the input signal by the subtracter 15, causing the cross talk to be erased. Accordingly, at the output of the BPF 13, the voice FM signal in which the cross talk is removed can be obtained and the voice bus interference can be prevented.
