摘　　要：阐述了FIR数字滤波器的窗函数设计方法,并利用Matlab语言实现了滤波器的设计与仿真。Matlab语言可以方便、快捷地设计具有严格线性相位的FIR系统,可节省大量的编程时间,提高编程效率,且参数的修改也十分方便。随着版本的不断提高,Matlab在数字滤波技术中会发挥更大的作用。This paper elaborates the FIR digital filter＇s windows function design method,and realizes the filter design and simulation by using the Matlab language. This Language can design the strict linear phase FIR system conveniently and quickly, also it can save many programming time, enhances the programming efficiency, and the parameter revision is also convenient. We believe that the Matlab language can play an important role in the digital filter technology with the improvement of edition enhancement unceasingly.
