Delay time adjusting method of delaying a phase of an output signal until a phase difference between an input signal and the output signal becomes an integral number of periods other than zero

摘要

A delay time adjusting method adjusts a delay time of an input signal so that a phase of the input signal and a phase of an output signal match each other. The delay time adjusting method comprises the step of delaying the phase of the output signal until a phase difference between the phase of the input signal and the phase of the output signal becomes N periods, where N is an integer other than zero.
