ABSTRACT:
An analog to digital converting system for a video signal is disclosed in which an analog video signal is fed to an analog to digital converter, then converted to a digital video signal, a digital burst signal is extracted from the digital video signal thus converted, the digital burst signal is multiplied by first and second AC signals having the same frequency as the burst frequency but different in phase to each other to produce first and second digital product signals, first and second digital signals representing DC components are derived from the first and second digital product signals, and the first and second digital signals are calculated to thereby control the phase of the sampling clock at the analog to digital converter.
