Abstract
In an odd side storage circuit, logical values of a decision subject signal HCMP are stored in first and second FFs respectively at decision edges LH and HL generated from odd-numbered edges of a decision edge EH. Logical values of a delayed decision subject signal HCMP′ are stored in third and fourth FFs. According to a selection signal generated by a selection signal generation circuit based on outputs of the third and fourth FFs, a first selector selects an output of the first or second FF. An even side storage circuit operates similarly at even-numbered edges. A second selector selects the odd and even side storage circuits alternately. The FFs in the odd and even side storage circuits are reset by a decision edge LH′ of the even side and the decision edge HL of the odd side, respectively.
