| Abstract: | This paper introduces how to extract the digital differential signal based FIR and IIR fliters in the digital differential circuit of the control system, and the way to improve the quality of the digital differential signals by some non-linear link such as dead zone and inertia, also in order to testify the accuracy of the method, we simulated the designed digital system and give the result. This method is proved to be simple, convenient and easy to be put into practice. |
