Abstract

PURPOSE:To quicken the phase drawing in without selecting the response, by stopping the functions of the phase comparison or the voltage control oscillator for a short time after the instruction of changeover and by position-synchronizing with the pulse reaching after the end of stop, in inputting a plural number of signals having equal center frequency with changeover.
