NOISE PULSE REMOVED CIRCUIT

摘要

This circuit efficiently removes noises by changing only counter setting value of a rectangular wave generating part without hardware modification. It comprises: (i) a rectangular wave generating means(22),(24),(25) being able to adjust duty togenerate a rectangular wave of low state; (ii) a delay element(21) that receives a rectangular wave with noise and outputs it with delay; and (iii) a logical AND operation means(23) that outputs a rectangular wave with removed noises.
