基于窗函数的数字FIR滤波器设计

Digital FIR Filter Design Based on Window Function

简要介绍了窗函数设计FIR滤波器的理论基础,运用Matlab语言实现了低通FIR滤波器的设计与仿真。窗函数法设计FIR滤波器具有设计简单、方便等优点。

The article simply introduces the design of digital FIR filter with window function,and realizes the design and emulation of low-pass filter by means of Matlab language. It is simple,convenient and useful to design FIR filter with window function.
