TF-analysis

较为详细地介绍了延迟微分方程的概念以及数值解法，并提供具体的计算案例以及在matlab中的实现，并附有一定的源码，适合初学者参考学习()

双音多频，由高频群和低频群组成，高低频群各包含4个频率。一个高频信号和一个低频信号叠加组成一个组合信号，代表一个数字。DTMF信号有16个编码。利用DTMF信令可选择呼叫相应的对讲机。(Dual tone multi-frequency, high-frequency and low-frequency group composed of groups, high-frequency group contains four frequencies each. A high-frequency signal and a low frequency signal is superimposed to form a combined signal representative of a number. DTMF signal has a 16 code. DTMF signaling to the appropriate use of the intercom call.)

matlab的另一个功能就是应用在图像处理上。有强大的能力处理图像。希望对读者有很大的帮助(Another feature is the application of matlab in image processing. Has a strong ability to handle images. Hope to be very helpful to readers)

用GA算法和ACO算法在MATLAB上解决TSP问题，附有31个城市的坐标数据(Coordinate data with GA algorithms and ACO algorithm in MATLAB to solve the TSP with 31 cities)

Bpsk simulation in matlab

基于互功率谱的时延估计，这个有中文注释，看得明白，光纤陀螺输出误差的allan方差分析。( Based on the time delay estimation of power spectrum, The Chinese have a comment, understand it, allan FOG output error variance analysis.)

介绍scott变压器基本原理，实现scott牵引变压器的仿真建模。(The basic principle of Scott transformer is introduced, and the simulation modeling of Scott traction transformer is realized.)

本程序是使用MATLAB语言采用迎风格式解对流方程，对流方程在工程上有很广泛的应用，而迎风格式的精度比较高还包括用跳点格式解扩散方程的初值问题，所以有两个程序 (This procedure is to use the MATLAB language solution using upwind convection equation, the convection equations in engineering, there is a wide range of applications, and the accuracy of upwind scheme also includes a relatively high point format with jump-diffusion equation solution of the initial value problem, so there are two procedures)
