摘要
就MATLAB在数字信号处理方面的应用作了一些研究,主要研究在MATLAB环境下FIR数字滤波器的典型设计方法:窗口法。列举具体实例比较了Hanning窗、Hamming窗、Blackman窗、Kaiser窗各自的频率响应曲线。应用MATLAB信号处理工具箱及其扩展函数,使得如何在数字信号处理过程中较复杂的数字滤波器设计问题得以解决,用MATLAB进行仿真设计,已成为实现FIR数字滤波器设计必不可少的实用技术。
Window law is a typical design method of the FIR digital filter design. This article mainly research the typical design method based on MATLAB in digital signal processing. At the same time this article particularizes the material examples to compare with their own frequency respond the curve of Hanning window, Hamming window, Blackman window and Kaiser window. Using signal processing kit and spread function of MATLAB can settle rather complicated design problems in course of digital signal processing. Simulation design based on already become nessesary applied technology of the FIR digital filter design.
