<p>PURPOSE:To provide a margin till a logic level is changed by making a change gradient in the rise or the fall of a delay pulse signal steep. CONSTITUTION:This processing circuit is provided with a ramp waveform generator 1 changing the change gradient of a leading edge or a trailing edge of an inputted pulse signal and outputting the result as a ramp waveform signal and also with a pulse signal generating circuit 2 controlling a timing to generate a pulse signal by adjusting a threshold level where the ramp waveform signal outputted from the ramp waveform generator 1 is sliced and generating a delay pulse signal delaying slightly the input pulse signal and with a change gradient correction circuit 3 changing steeply the change gradient of the rise or the fall of the delay pulse signal.</p> |
