A signal processing system of incremental encoder is introduced,which can realize the operations of fourfold fre?quency phase discrimination,counting and reset. The final counting results are uploaded to the upper computer via EMIF inter?face. The design was simulated with Modelsim software and tested on the test platform. The experimental results are analyzed, and show that the counting value of this design is accurate and reliable. The system has strong anti?interference ability.
