说明：  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 approximate methods are a window function method, frequency sampling method, the best uniform approximation method. Here only to discuss the window function method. Procedure is also adopted this approach.)

LMS滤波算法，分别对锯齿波、方波、正弦波进行了滤波，并将滤波前后的信号进行了对比，很好的恢复出了真实信号。(LMS filter algorithm. The sawtooth wave, square wave, sine wave are filtered, and the signals are contrasted before and after filtering. The real signals are all well recoveried by this algorithm.)

matlab中关于信号处理的内容及代码，非常有用~~(matlab signal processing on the content and code, very useful ~ ~)

Some methods Applied in matlab

RS编译码的matlab码源，经测试好用。(RS codec matlab source code)

k程序差分进化工具箱 - DeMatMATLAB包括拥有数百个内部函数的主包和三十几种工具包。工具包又可以分为功能性工具包和学科工具包。功能工具包用来扩充MATLAB的符号计算，可视化建模仿真，文字处理及实时控制等功能。学科工具包是专业性比较强的工具包，控制工具包，信号处理工具包，通信工具包等都属于此类。(k programs differential evolution toolbox- DeMatMATLAB including internal functions with hundreds of primary packages and several 30 kits. Kits can be divided into functional disciplines toolkit and toolkit. Function tool kit used to expand the MATLAB symbolic computation, visualization, modeling and simulation, word processing, and real-time control functions. Discipline tool kit is relatively strong professional toolkit, Control Toolkit, signal processing toolkit, communications toolkit belong to this category.)
