PURPOSE:To perform synchronization without causing unbalance in drawing between two different frequencies by inputting an input signal to a circuit with two kinds of delay time. CONSTITUTION:Through time regulator 7, an input signal is supplied to a circuit with two kinds of delay time and while TdA>TdB, signals B1 and B2 are delayed by TdA and TdB respectively. When the pulse width of the input signal is T3 and that of output B3 of reference pulse generator 1 is TMS, the operation is so carried out that the falling point of signal B3 will agree with the rising point of signals B5. Here, signal B2 is matched by adjusting TdB to the rising point of the pulse preceding the agreeing pulse by one, so that the rising point of signal B2 will agree with the center position of the pulse width of signal B6. Namely, the signal B2 is matched with the half-bit succeeding position. |
