Abstract
A phase shift between two repeated square wave signals having equal frequency and duty is detected and detected phase shift is integrated during the appointed cycles of the square wave signals and the mean value per cycle is calculated from the integrated value, and a phase of one signal is overlapped on a phase of another signal automatically at the mean value. The same phase can be automatically given to two square wave signals having different phases.
