发明名称 Crosstalk attenuator system
摘要 Disclosed is a crosstalk attenuator system for reducing the crosstalk which occurs at the time of separating and reproducing the original signals from the video disc recording medium on which a video signal and a voice signal have been recorded as a compound signal on the same track. In the system, a first multiplier receives both the signals separated from the medium to analyze the relative relation between the signals and thus to generate an output signal according to the amount of the crosstalk between the signals; a second multiplier receives the output signal and one of the signals to generate a feedback signal equivalent to the other crosstalk signal component mixed in one signal, and the feedback signal is subtracted from the other signal component thereby to reduce the crosstalk.
