@@@@The digital filter is one of the most important parts of digital signal processing, thus its theory design process is very complex. In this paper, we take Matlab as a tool to introduce the use of infinite impulse response digital filter in the separation of complex signal, and also to gain the simulation results. Practice shows that using Matlab in the"digital filter design” course teaching can not only enhance the students’ perceptual understanding, but also help students understand and grasp the basic principle and design methods of digital filter, meanwhile it trains the hands-on practical ability and creative consciousness of students.
