Title: Ghost eliminator
Inventor: TANAKA TADAAKI
IPC: H04N5/21
Filed: 1987-01-31
Abstract: PURPOSE:To perform the elimination of a ghost satisfactorily without shortening a sampling cycle, by attaching a delay time equivalent to the deviation of a timing between a sampling time and an origin in a tap gain control part on a pseudo ghost signal. CONSTITUTION:An origin deciding part 12 in the tap gain control part 1 monitors the output television signal of an A/D converter 11, and detects a sampling point nearest to each center part of a reference waveform and a ghost waveform, and decides it as the origin. The origin deciding part 12 calculates the deviation of the timing between the sampling time and the origin. The origin deciding part 12 controls the delay quantity of a variable delay circuit 6 by a time corresponding to the deviation. A tap gain corresponding to the ghost outputted from the tap gain control part 1 is inputted to a transversal filter which constitutes a pseudo ghost generating part 2. The output of the pseudo ghost generating part 2 is delayed by the delay time corresponding to the above stated deviation of the timing by the delay circuit 6, and is outputted to an adder 4 for offsetting the ghost.
