基于Matlab GUI的数字滤波器设计及其应用

Design of digital filters based on Matlab GUI and their application

基于数字信号处理原理,在分析数字滤波器设计理论和Matlab编程技术及其GUI图形用户界面设计的基础上,开发了具有交互式特点的数字滤波器软件,界面操作简单方便,可以根据需要选择滤波器类型,输入相关参数,然后选择相应的功能按钮,就可以得到滤波器的特性参数,并进行滤波器的性能分析,打破了以往滤波器设计过程中大量繁琐的数值计算问题,为数字滤波器的设计和应用提供了一个有效的辅助工具。

Based on the principles of digital signal processing and Matlab GUI programming techniques, analysised the digital filter design theory ,developed an interactive software to design digital filters. Its operation interfaces are very simple, software users can select one type of filters, input parameters, and then select the corresponding function button, the filter characteristic parameters and performance analysis can be obtained. It breaks tile previous filter design process, which has a large number of complicated numerical problems.It supplys an effective aids for the digital filter design and application.
