Passband-linear-phase IIR EQ design with poles and zeros

基于costas环路的载波同步，使收发时钟频率和相位一致，环路包括四个部分乘法器和低通滤波、鉴相器、环路滤波器和数字振荡器组成(Based on the carrier synchronization of Costas loop, the frequency and phase of the transmit and receive clock is the same. The loop consists of four parts, including the multiplier and low-pass filter, phase detector, loop filter and digital oscillator.)

假设一物体围绕一圆周运动，角加速度是白噪声，观测噪声也是零均值的白噪声。编程使用卡尔曼滤波器实现运动物体的跟踪。(Suppose an object around a circular motion, the angular acceleration is white noise, measurement noise is zero mean white noise. Programming using a Kalman filter to achieve tracking moving objects.)

条件概率搜索算法，简单，有效，经调试可用！(Conditional probability search algorithm, simple, effective, can be used by debugging!)

The files explain aliasing , gibbs, dft and fft. All are very useful in signal processing applications and the files illustrate the contents very well with plots/graphs.

采用Matlab编写的弹道分析算法，该算法可以模拟弹道飞行轨迹(Matlab preparation of the trajectory analysis algorithm, which can be simulated ballistic trajectory)

该文件是用MATLAB来进行随机数的产生，有具体的算法的实现。(This file is used MATLAB to carry out random number generation, there is a specific algorithm.)

addmitance matrix for solving load flow analysis

模式识别的fisher线性判别方法，包括学习文档和实验源代码。(Fisher linear discriminant pattern recognition methods, including documents and experiment to learn the source code.)

说明：  利用MATLAB进行数据拟合，常见的数据拟合方法。包括：一元函数插值、样条插值、多项式插值或拟合 、曲线拟合、拉格朗日插值法等。(MATLAB data fitting, common data fitting methods. It includes: interpolation of unitary function, spline interpolation, polynomial interpolation or fitting, curve fitting, Lagrange interpolation, etc.)
