ABSTRACT:
An input synchronizing signal is subjected to mean DC voltage adjustment so that the mean DC voltage thereof becomes a prescribed level. The input synchronizing signal after the mean DC voltage adjustment is compared with first reference voltage which is higher than the prescribed level and second reference voltage which is lower than the prescribed level by comparators, to derive an output synchronizing signal of constant polarity and amplitude or a polarity detection output for the input synchronizing signal.
