ADAPTIVE GHOST CANCELLING APPARATUS

摘要

the first filtering means(10) to perform an FIR(Finite Impulse Response) filtering; a control means(30) to control the center tap of the first filtering means(10) automatically by generating a control signal; and the second filtering means(20) to perform an IIR(Infinite Impulse Response) filtering to remove a long ghost as to the input video signal by the second filtering of the first-filtered video signal and by a feedback of the second-filtered signal.
