Technical Examples
  1. A phase difference between a first periodic signal, and a sample signal corresponding to a second periodic signal and having a predetermined signal resolution M is calculated in a phase comparing method. The sample signal is obtained by sampling the second periodic signal at a sampling frequency fs for one signal cycle of the second periodic signal when a frequency of the second periodic signal is not greater than an allowable sampling signal frequency fab equal to fs/M or by conducting at least one of sampling the second periodic signal at fs for more than one signal cycle of the second periodic signal, and generating interpolated values for the sample signal after sampling the second periodic signal at fs in accordance with whether or not M/N yields a remainder and whether or not N is a prime number when the frequency of the second periodic signal is greater than and is N times fab.
