摘　　要：数字滤波器是数字信号处理中的重要组成部分,其理论实现过程比较复杂.本文以Matlab为工具,介绍了IIR数字滤波器在复合信号分离中的应用,并给出了仿真结果.实践表明,将Matlab应用于"数字滤波器设计"课程教学,可增强学生的感性认识,有助于学生理解与掌握数字滤波器的基本原理和设计方法,锻炼学生的动手实践能力和创新意识.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.
