数字信号处理 传统的宽带信号中抑制正弦干扰的方法是采用陷波器(notch filter),为此我们需要精确知道干扰正弦的频率.然而当干扰正弦频率是缓慢变化时,且选频率特性要求十分尖锐时,则最好采用自适应噪声抵消的方法.下图是用一个二阶FIR的LMS自适应滤波器消除正弦干扰的一个方案。(DSP)

非常好的函数程序,关于超宽带的,省了不少事情啊(very good function procedures for UWB, save a lot of things ah)

这是John Wiley出版的<Computational Colour Science using MATLAB.e2ban>教科书书附带的程序代码,自成一体为Matlab下的色度学工具箱. 建议将解压文件放到本地机已经安装Matlab的路径中,在toolbook文件夹下自己创建一个名为colour的文件夹中.比如:For example, this may be c:Program FilesMATLABp65 oolboxcolour 但具体路径取决于Matlab在你机器中的安装路径. 如果你将该colour文件夹加入Matlab环境路径中,该工具箱就与其它工具箱一样使用.-This is John Wiley published(It is published by John Wiley <Computational Colour Science using MATLAB.e2ban> Textbook book accompanying program code, self-contained for the colorimetric under Matlab toolbox. Suggested extracting file on the local machine has been installed in the path of Matlab in toolbook folder create yourself a folder named colour For example: For example, this may be c: Program Files MATLABp65 toolbox colour but the exact path depends on your machine Matlab installation path if you join the colour folder path in the Matlab environment, the tool box to use the same connection with other toolkits.-This is John Wiley published)

根据系统辨识的系统模型，采用KALMAN滤波算法，根据期望信号和观测信号求未知的系统。(According to the system model system identification, using KALMAN filtering algorithm, based on the desired signal and the observed signal seeking unknown system.)

Chapter 5 Matlab codes from AEMM book

说明：  The program can detect the phase difference between one Sinoid signal with another sinoid signal and can generate a new signal of same phase

基于IMM多模型结构的带自适应渐消因子及衰减因子的无忌卡尔曼滤波器。 适用于非线性、模型不准确、噪声不确定情况下滤波(IMM multi-band adaptive model structure based on fading factor and the attenuation factor of the wild and the Kalman filter. Applies to non-linear model is not accurate, noise filtering uncertainty)

说明：   基于matlab 的叠加高斯白噪声的正弦信号频谱分析，给定正弦函数x=sin(2πf0n/N+π/3)+sin(2πf1n/N+π/4)，设定f0.f1的值，加了噪声之后做快速傅里叶变换，在matlab中分析其频谱，验证是否与f0,f1的值符合。再变换N值，看随着N值的变化对应点是否符合及有何变化。(Matlab based on the superposition of Gaussian white noise sinusoidal signal spectrum analysis, given the sine function x = sin (2蟺f0n/N+蟺/3)+sin (2蟺f1n/N+蟺/4) set value of f0.f1, do a quick noise Fourier transform to analyze the spectrum in matlab, verify that with f0, in line with the value of F1. Transform the value of N, see change as the value of N corresponding points of compliance and what changes.)

基于matlab的四象限直线和圆弧插补程序，另附有GUI设计文件（已验证可用）(Matlab-based four-quadrant linear and circular interpolation procedures, there are GUI design documents attached (verified available))

matlab pll仿真，利用.m文件编写，可用做了解PLL的资料(matlab pll simulation using the. m documentation, can be used to understand the data PLL)
