ABSTRACT:
Provided is an apparatus comprising a delaying section that generates a plurality of delayed signals by delaying a single first input signal by different delay amounts; a first acquiring section that acquires each of a plurality of input second input signals at a first phase of a reference clock; a second acquiring section that acquires each of the plurality of second input signals at a second phase of the reference clock, which is different from the first phase; and a change point detecting section that detects a change point of one of the first input signal and a second input signal, based on values of the plurality of signals acquired by the first acquiring section and values of the plurality of signals acquired by the second acquiring section.
