ABSTRACT:
A ghost signal suppressing device comprises a circuit for suppressing the luminance signal of a ghost signal and a circuit for suppressing the color signal of the ghost signal. A delayed signal used for suppressing the ghost signal is produced at a single delay circuit and branched off to be used for both the suppressing circuits. The branched signals of the same delay time are individually adjusted in their amplitude and then subtracted from an original signal at the respective suppressing circuits.
