FIR数字滤波器的设计方法主要是建立在对理想滤波器频率特性作某种近似的基础上的。这些近似方法有窗函数法、频率抽样法、最佳一致逼近法。在这里只讨论窗函数法。程序中也是采用了这种方法。-FIR digital filter design method is mainly based on the frequency characteristics of the ideal filter for some kind of approximation on the basis of. These app

数字信号处理技术基于Mathlab的FIR等滤波器的仿真源码-Digital signal processing technology is based on the Mathlab simulation of FIR filter, such as source

Matlab数字信号处理与应用源代码，这是一本书上的关于matlab的源代码，对于学习小波变换的初学者可以参考一下啊。-Application of digital signal processing and Matlab source code, this is a book on matlab source code for beginners to learn on wavelet transform for reference ah.

当出现Undefined fuction ideal_lp for input arguments of type double .时检查工具箱是否有理想滤波器工具，若有，请检查参数 若没有，请将如上代码转为.m文件并添加。-When an Undefined fuction ideal_lp for input the arguments of the type double . Check the toolkit for ideal filter tool, if yes, pleas
