PULSE SIGNAL GENERATING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a pulse signal generating circuit capable of generating a pulse signal with a prescribed time width based on a pulse signal received at last even when plural consecutive pulse signals are received as input signals. SOLUTION: A pulse width setting circuit 41 generates a pulse OUT with a prescribed preset time width and provides an output of it based on a change in an input signal NP. A reset circuit 42 outputs a reset signal RS to the pulse width setting circuit 41 when the input signal Np changes at a shorter interval than the set time width by the pulse setting circuit 41 and allows the pulse width setting circuit 41 to output a pulse OUT with a prescribed time width based on the input signal NP received later.
