| Abstract: | Since the traditional grating subdivision direction discrimination circuit features slow reaction rate and complex circuit,the paper proposes a new way to realize the logic circuit.Through the thorough analysis of grating signal four subdivision direction discrimination algorithm,the Verilog HDL language is employed to implement the logic of the algorithm.The theoretical calculations and simulation indicates that the four subdivision and direction discrimination algorithm of grating signal is of high accuracy,broad measurement range,simple logic circuit and good reliability. |
