基于SystemView的数字滤波器仿真与分析

文章针对数字信号处理课程课堂教学理论性强的特点，提出利用SystemView软件平台对重要知识点数字滤波器的设计进行辅助教学。在数字信号处理中，滤波器占有极其重要的地位，是所有通信系统中必不可少的部分。传统的滤波器的设计过程很复杂，计算工作量也比较大，而且滤波特性调整困难，影响了它的应用。文章利用SystemView的滤波器设计功能，完成IIR和FIR滤波器的设计，并对滤波器的幅频特性、相频特性等性能加以分析，通过仿真表明所设计的数字滤波器技术指标完全符合设计要求，而且实现了滤波器设计的简单化，具有实用价值。

Simulation and analysis of digital filter based on System View

According to the characteristics of being rather theoretical in the course Digital Signal Processing,this paper puts forward that System View software platform can be used to assist the teaching of digital filter design.In digital signal processing,filter occupies an extremely important position and is an essential part of all the communication systems.The design process of the traditional filter is very complex and the calculation is big.In addition,the adjustment of the filter characteristics is difficult...
