Abstract
A sync signal generator of a television receiver for use in a vehicle has a phase reset detector for gradually absorbing a phase fluctuation of an input sync signal which occurs due to a ghost phenomenon or a fading phenomenon and reducing a phase fluctuation. The sync signal generator provides a sync signal synchronized with an output signal of the phase reset signal detector. Thus, a stable sync signal without a sudden change in phase can be obtained although it is synchronized with the input sync signal.
