A MISCONDUCTION PREVENTION APPARATUS OF GHOST CANCELLER

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ghost eliminator that removes ghosts generated by reflected waves during terrestrial broadcast transmission of television signals. In particular, a GCR signal and a reference CGR that have passed through a ghost eliminator by a malfunction control signal generator in order to prevent malfunction of the ghost eliminator. Ghost that selects and outputs the image signal passing through the ghost eliminator only when the correlation value of the signal is larger than the reference value and the sum of the ghost elimination filter coefficients is greater than the sum of the sum of the filter coefficients for determining the stability of the filter. Malfunction prevention device of eliminator.
