PURPOSE:To set variably the leading edge and the trailing edge by generating a switching control pulse in accordance with a time delayed by a delaying circuit for correction, and also in accordance with the output of a coarse adjustment timing pulse generating circuit, and generating selective gate operation by its pulse. CONSTITUTION:The leading edge of output pulse of a coarse adjustment timing pulse generating circuit 1 is delayed by a time tON determined by a delaying circuit 10 and outputted. On the other hand, its trailing edge is delayed by a time tOFF determined by a delaying circuit 12 and outputted. Its time tON is determined by a delay time of output of the circuit 10 selected by the value set to a register 10b. Also, the time tOFF is determined by a delay time of the output of the circuit 12 selected by the value set to the register 12b. Therefore, the leading edge of the output timing pulse and also the trailing edge can be set variably. |
