Abstract

PURPOSE:A rectangular wave signal including noises is used as a gate signal to compute a clock pulse, and said noises are removed by using the fact that the pulse width of the noises in narrower than the pulse width, which shows a dowel angle, thus obtaining high accuracy, dowel angle measuring device.
