Abstract
A device and method for detecting a period of an input signal including a count value setting portion; an A/D converter; a zero cross point detecting portion to detect a symbol change of digital values received from the A/D converter; a arithmetic processing unit; a counter; and a period value calculating portion. The arithmetic processing unit divides two sampling sectors, having a zero cross point in their center, by a preset value which is set in the count value setting portion, predicts a zero cross point sector based on the digital values of two sampling points, and calculates a count value of the reference clock in accordance with the predicted zero cross point sector and the preset value which is set in the count value setting portion.
