ABSTRACT:
Phase synchronization is achieved by forming a first pulse to be synchronized with a reference pulse, a second pulse leading in phase for a certain period relative to said first pulse and a third pulse delayed in phase for a certain period from said first pulse; comparing said reference pulse with said first pulse in a first comparing; comparing said reference pulse with said second pulse and said third pulse in a second comparing; and forming a control voltage by giving priority to a comparison output of said second comparing with respect to a comparison output of said first comparing, matching the phase of said reference pulse with the phrase of said second pulse or said third pulse, and matching, after said matching of phases, the phrase of said reference pulse with the phase of said first pulse by forming said control, voltage from the comparison output of said first comparing.
