Abstract

PURPOSE:To eliminate ghost surely by inputting the video signal, which has high- band components emphasized, to the delay circuit through the frequency characteristic correcting circuit, in the unit which generates a cancel signal simulative of ghost to eliminate ghost. CONSTITUTION:Cancel signal S3 simulative of ghost is generated by delay circuit 4, multipliers 51-5N, adder 6 and demultiplexer 7. Meanwhile, video signal Sd is supplied from terminal 1. The output of adder 13 is subtracted from the output of the center tap of delay circuit 10 by a synthesizer, and the waveform differentiated by differentiating circuit 15 is supplied to demultiplexer 12 to give a multiplication coefficient to multipliers. Output video signal Sd1 of frequency characteristic correcting circuit 9a obtained from synthesizer 14 has high-band components emphasized, and therefore, cancel signal S1' approaches impulse response of ghost, and thus, ghost is eliminated surely.
