摘要
数字滤波器作为数字信号处理的基本组成构件,其设计在数字信号处理中有着重要的意义。本文根据FIR数字滤波器设计的基本原理,提出了基于MATLAB的FIR数字滤波器的窗函数设计法。文中给出了设计实例,仿真结果表明设计的各项性能指标均达到了指定要求,设计过程简便易行。
Digital filter is the basic components of digital signal processing, the design of it has an important meaning for the digital signal processing. This paper proposes the method of using window function to design FIR filter based on MATLAB, according to the design basic principle of FIR digital filter. In the paper, the simulation result shows that the designed filter can meet the requirements very well and the design procedure is simple and practical.
