Abstract
Disclosed is a phase control system for providing by digital processing a timing signal having a certain phase relationship with a timing signal detected in a received, modulated signal, wherein the detected timing signal is delayed by a predetermined time period and the detected timing signal and the delayed timing signal are multiplied by respective constants so that the zero-cross point of the composite signal of the two timing signals matches the sampling point of the timing signal.
