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. U = C - 1 N  ∑ j = 1 L   G j ( Formula   1 )

Claim (Index 6):
The phase difference measurement device according to  claim 4 , wherein, when a sampling rate for driving the AD converter is indicated by f ADC , and an averaging count of the averaging processor is indicated by N, a phase difference calculation rate obtained in the averaging processor is f ADC /N.
