Abstract:
This phase measurement device is provided with: a count processor  4  that counts a zero crossing detection count C, which is the number of times a change in the sign of a digital signal has been detected; and a fraction processor  5  for calculating a fraction F j  (j=1 to L) of the zero crossing detection count on the basis of the digital signal at sampling timings immediately before and immediately after a zero crossing specification means has determined a zero crossing, and computing a fraction processing parameter G j =N j −F j  using a zero crossing detection number N j  (1≤N j ≤N) in a period corresponding to a sampling count N necessary for averaging determined in advance. The averaging is performed according to the following formula, where C is the output of the count processor at the end of an averaging period and G j  (j=1 to L) is L fraction processing parameters computed by the fraction processor, and the phase of the digital signal is computed, whereby the phase is calculated on the basis of an input signal digital value obtained by an AD converter.

Claim (Index 1):
A phase measurement device that measures a phase of a periodic input signal varying periodically through a digital circuit, comprising:\n an AD converter that digitizes the periodic input signal at each predetermined sampling timing and outputs a digital signal; a zero crossing specification means that detects a change in a sign of the digital signal; a count processor that counts and calculates a zero crossing detection count C through the zero crossing specification means at each sampling timing; a fraction processor that calculates a fraction F j  (j=1 to L) of the zero crossing detection count on the basis of the digital signals at sampling timings immediately before and immediately after the zero crossing specification means determines zero crossing and further calculates a fraction processing parameter G j =N j \u2212F j  using a zero crossing detection number N j  (1\u2264N j \u2264N) in a period of a predetermined sampling count N (the number of data to be averaged) necessary for averaging; and an averaging processor that averages the count processor calculation value C when the period ends and L fractions calculated by the fraction processor in a period of the sampling count N using Formula 1 and calculates a phase of the digital signal.
