Title: Ghost eliminating device
Inventor: MURATA TOSHINORI
IPC: H04B3/06
Filed: 1984-12-26
Abstract: PURPOSE:To facilitate ghost detection due to a clock by amplifying an input signal to a transversal filter while the ghost is eliminated and restoring the input signal toa prescribed value after the ghost is eliminated. CONSTITUTION:Switches 15 and 16 are switched to the contact A side at a power-on time and a channel selection time. As the result, the signal amplified by an amplifier 14 is inputted to a transversal filter 3. With respect to the output of a ghost eliminating circuit, the input signal with the ghost added is outputted as it is. Meanwhile, a counter 17 counts a reference signal. Since differential output pulses are increased in a differentiating circuit 6, S/N of ghost detection is improved. Therefore, the ghost suppressing effect is improved even if the ghost included in the inputted signal is weak or differential pulses are reduced according as the ghost is eliminated. Thus, switches 15 and 16 are switched to the contact B side when the counter 17 counts a prescribed number by the progression of the ghost eliminating operation.
