Amplitude_Modulation

用matlab开放环境实现了对数据的非线性回归，方便好用，直接将数据输入到程序中，便可以实现对数据的非线性回归(Open environment with matlab realize the non-linear regression of data, easy to use, enter data directly into the program, you can achieve non-linear regression of the data)

Compare FDM and FEM method in 1D

本文件包含两个程序，实现一维和二维分形地面的模拟(This document contains two procedures to achieve a one-dimensional and two-dimensional simulation of the ground, Fractal)

采用信号包络和差分方式进行信号模式识别，通过变换产生时域解析信号SKH ，即信号的复包络，得到零中心归一化瞬时绝对值的标准偏差。 (Differential use of signal envelope and the way the signal pattern recognition, transformation generated by time domain analytic signal SKH, the signal complex envelope, zero-center normalized standard deviation of the instantaneous absolute value.)

关于一篇英文论文中峭度谱分析方法的变成，用于轴承故障诊断中。(A paper on a English kurtosis spectrum into analysis method, used for fault diagnosis of bearing.)

系统深入得多，一些在第一本中只略微论及的高级内容，这里讲得完整透彻。理论与实践并重，可操作性强。例题都有可直接运行的matlab文件，正文中也给出了关键部份方便阅读。读完这本书，住真水平可以上一个台阶，基本上可以达到系统级仿真的能力。(System is much more depth, some in the first book deals with only a slight premium content here put a complete and thorough. Theoretical and a practical, easy to operate. Example are directly run matlab file, the text also gives a key part of user-friendly. After reading this book, the level of living can be really a new level, but basically can achieve system-level simulation capabilities.)

电话线出现断线或短路故障时，线路的阻抗则发生很大变化，利用电桥法测试出电阻的大小，进而得出线路故障的地方(Telephone lines appear disconnection or short circuit fault, the line impedance is changed, test out the size of resistance by Wheatstone bridge method, and then draw the line fault place )

说明：  波达方向估计 应用最常规的MUSIC算法 实用！(Direction of Arrival Estimation most conventional MUSIC algorithm practical!)

Converts binary data of any format in a string to floating point decimals of a defined fraction size. the intsize input parameter defines the size of the exponent and sets the fixed point location in the binary number. se accompanied matlab program for test of this function
