Frame synchronization apparatus, measurement apparatus including the same, frame synchronization method and measurement method

摘要

To provide a frame synchronizer capable of shortening the processing time of frame synchronization processing.SOLUTION: A frame synchronizer generates a frame trigger 70 including frame triggers 71, 74 with a time period of frame length, captures a capture signal 81 including a frame 2 from an input signal 60 with reference to the frame trigger 71, detects the head position 62 of the frame 2 included in the capture signal 81, detects the time from the frame trigger 71, as the reference, to the head position 62 of the frame 2, as a reference time Ts, captures a capture signal 82 including a frame 12 from the input signal 60 with reference to a frame trigger 74 after the reference time Ts is detected, and then detects the head position 64 of the frame 12 on the basis of the reference time Ts.SELECTED DRAWING: Figure 2
