In order to solve the problem of big difference between simulation process and actual application process this paper takes the signal filtering in electrical circuit system as an example,to present a design method of digital filtering system.Using relevant modules provided by the software of SIMULINK/SIMSCAPE,some electrical circuits are built,and combing some programming skill,triggered subsystem from SIMULINK modules is used to simulate the process of periodical sampling,periodic calculation of difference equation.Furthermore,relevant programming idea is introduced by the implement of a first order low pass filter.Finally,simulation results show the efficiency of the proposed method.
