Abstract

PURPOSE:To perform accurate pulse detection by detecting the rises and falls of two pulse signals and by making a direction decision under the AND conditions. CONSTITUTION:As pulse signal A rises, rise detection part 18 outputs an output signal and when pulse signal B is at H at this time, RS flip-flop 26 is set. Next, as pulse signal B falls, fall detection part 21 sends out an output signal to AND gate 25, which sends out an output signal. Since the output of RS flip-flop 26 is at H, it is supplied to AND gate 28, which outputs a pulse signal. Therefore, even if chattering occurs after the fall of pulse signal A, nothing is generated because pulse signal B is at L.
