ABSTRACT:
A periodic function wave generator is provided in a digital phase synchronizing circuit which comprises a memory circuit for storing the values of n phases obtained by equally dividing one period of a sine wave by 4n and each having a phase .theta.=90.degree.
(i+0.5), where n represents an integer and i is an integer of from 0 to n-1, a circuit for designating a predetermined one of these phases in one period, a circuit for converting an address read out of the memory circuit into one of the n phases in accordance with one of the ranges of 0.degree. to 90.degree., 90.degree. to 180.degree., 180.degree. to 270.degree. and 270.degree. to 360.degree. and a circuit for inverting the sign of the output of the memory circuit in accordance with the particular range in which the designated phase falls.
