摘要
A period estimation apparatus includes processing circuitry configured to extract candidate periods being a target of period determination from an input pulse train, use at least one of the candidate periods extracted to determine whether the at least one of the candidate periods exists as an actual period, and, when determining that the at least one of the candidate periods does not exist as the actual period, suspend the period determination for the at least one of the candidate periods, perform the period determination for the at least one of the candidate periods determined to exist as the actual period, generate a pseudo periodic pulse train, adjust, based on a differential value between the pseudo periodic pulse train generated and the input pulse train, a pulse position of the pseudo periodic pulse train, and detect a periodic pulse train according to results of the period determination and adjustment.
