<p>PURPOSE:To obtain an output signal without jitter held at a prescribed phase by dividing an input signal at the pahse location of a leading edge or a trailing edge of an output signal in two peak value distributions into two so as to apply phase control. CONSTITUTION:Phase control means 17, 18, 19 output a control signal to bring an input signal to a phase location in response to a phase difference outputted from the 1st phase difference output means 24, 27 when the input signal divided by signal discrimination means 14, 15 into two is at one phase location. If the input signals divided into two by the signal discrimination means are at the other phase location, the phase control means output a control signal to bring the input signal to a phase location in response to the phase difference outputted from the 2nd phase difference output means 25, 29. Thus, the output signal held at a prescribed phase and inserted between the distributions of the input signal having the phase of two peak value distributions is produced.</p> |
