Abstract
A periodic signal detector includes sample counting means for counting a number of samples between adjacent zero cross points in an input signal, the sample counting means outputting the number of samples between each time the number of samples between the adjacent zero cross points is obtained and continuing outputting the number of samples until a next zero cross point is detected, and periodic signal section detecting means for detecting a section, as a periodic signal section, in which the output from the sample counting means has a constant result.
