<p>PURPOSE:To output a prescribed pulse width independently of an interval of an input signal by adding a delay circuit retarding a trigger signal, a NOT gate inverting an output of the delay circuit, an AND gate ANDing the output of the NOT gate and the trigger signal and an OR gate adding the output of the AND gate to a comparison output. CONSTITUTION:A delay circuit 10 retarding a trigger signal, a NOT gate 11 inverting an output of the delay circuit 10, an AND gate 12 ANDing the output of the NOT gate 11 and the trigger signal and an OR gate 13 adding the output of the AND gate 12 to a comparison output of a comparison means 8 comparing a charging voltage of a capacitor and a reference voltage are provided to the circuit. Then the capacitor 6 is discharged at every input of the trigger signal. Thus, a pulse with a prescribed pulse width is outputted independently of an interval of an input signal.</p> |
