【Abstract】 This paper introduces a principle of detecting angle displacement and the realization of hardware circuit of signal handling. By processing the signals output by the increment encoder, the forward and backward judging signals and the four multiplying frequency counting pulse can be acquired. The accurate detection about the angle displacement is realized.更多还原
