Abstract
A frame signal generator is configured to generate a frame signal with a predetermined first time length from an input signal. A reference signal generator is configured to generate a reference signal from a signal located more in a past than a position of the frame signal in the input signal. A correlation value calculator is configured to calculate a correlation value between the frame signal and the reference signal within a range of a predetermined phase shift amount m. A periodic noise determiner is configured to determine whether or not the frame signal includes periodic noise, and calculate a period of the periodic noise in the case where the frame signal includes the periodic noise. A correlation value calculation range generator is configured to generate the range of the predetermined phase shift amount based on the period of the periodic noise.
