AUTOMATIC PHASE MATCHING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide the automatic phase matching device which can match phases even when there is a >=1/2 phase difference. SOLUTION: Two pieces 101 and 102 of information are written in delay insertion circuits 103 and 104 with respective frame phases, frame by frame. A delay setting circuit 1 selects one of the frame phases 6 and 7 and reads the two pieces of information of one frame out with the frame phase. The two read pieces of information are compared by a comparing circuit 4 and when they do not equal to each other, the delay setting circuit 1 performs switching to the other frame phase to read two pieces of information of a following frame out.
