Abstract
PURPOSE: To enable measurement without being subject to the variation of waveform caused due to various causes, by obtaining the phase difference through the addition of the time between the front edges and that between rear edges of the rectangular wave obtained from two signals to be compared.
CONSTITUTION: The phase difference between two signals is measured by measuring the time T1, T2 between the front and rear edges of two rectangular waves C and D adding T1 and T2. The time between the time centers S1 and S2 of the signal waveform to be compared is constant, if the phase difference is constant, and the increase or decrease in the waveform is caused symmetrical toward the front and rear edge by taking the centers S1 or S2 as the center, then the time adding the time T1 between the front edges and the time T2 between rear edges of the both waveforms corresponds to the phase difference. This thinking can be applied to the trapesoid such as isoscales triangle and isoscales trapesoid, not limited to sinusoidal waves.
