Abstract
A third periodic signal is synthesized using a first output signal having a phase corresponding to a first periodic signal and a second output signal having a phase corresponding to the second periodic signal. A value of the third periodic signal is detected at a timing of the phase of the delayed first periodic signal. The value of the third periodic signal detected with the delayed first periodic signal is compared with the value of the third periodic signal detected by the first periodic signal delayed by the different delay amount. The delay amount is obtained for the detected third periodic signal being a maximum or a minimum. In a state of the optimum delay amount, an amplitude of the third periodic signal is adjusted so that the detected value of the third periodic signal falls within a predetermined range.
