摘要
数字滤波器设计是数字信号处理的重要组成部分。文章介绍了基于Matlab编程环境下用窗函数设计法,频率采样法,频率交换法,实现FIR二维数字滤波器的设计,并给出了设计实例仿真。设计结果表明,利用Matlab软件设计数字滤波器简便、易行。
The design of digital filter is one of the most important parts in signal processing. This article introduced using window function method frequency sampling method and frequency exchange method to implement the design of 2D FIR digital filter based on Matlab programming environment and gave example of simulation. The result indicates that using Matlab to design digital filter is very simple.
