MATLAB 下的数字信号处理实现示例 包括: 单位脉冲序列 矩形序列 特定冲击串 卷积计算 卷积定律验证 (MATLAB under the realization of digital signal processing examples include: unit rectangular pulse sequence sequence-specific impact of the law of string convolution convolution calculation to verify)

T2F子函数，在做傅里叶变换时调用。我一开始编程序时忘了加它，结果WARN ME 说未定义T2F。(T2F subroutine, called when doing Fourier transform. I started to compile the program forgot to add it, and the result is undefined WARN ME said T2F.)

OFDM的调制过程，已经运行过，比较不错，过程很清晰(OFDM modulation process has been run before, quite good, the process is very clear)

利用符号计算推导光学三阶微环滤波器传输函数，代入参数计算光谱响应，并对关键参数做扫描，绘制4通道微环滤波器响应谱。(Utilizing symbolic computation to derive the third-order optical micro-ring filter transfer function, substitutes the parameters to calculate the optical response. The key parameters are swept and the optical response of a four-channel micro-ring filter is drawn.)

Frequency response of second order system

2017年0616，该频域分解（FDD）土木工程中的一个输出系统识别技术的流行，特别是在结构健康监测。作为一个输出的算法，它是有用的当输入数据是未知的。FDD是模态分析技术，生成系统的实现采用了频率响应（多）输出数据参考。所附的MATLAB代码实现了这一技术的模态参数识别。为了使用此代码，处理（趋势、过滤等）时间的历史数据必须存储在一个Excel文件（数据每一频道栏目）。检查“加速度。对于时间的历史文件的一个实例xlsx”。(In 2017, 0616, frequency domain decomposition (FDD), an output system in civil engineering, was popular in identification technology, especially in structural health monitoring. As an output of the algorithm, it is useful when the input data is unknown. FDD is a modal analysis technique, and the implementation of the system adopts a frequency response (multiple) output data reference.)

说明：  matlab的60个小程序，很实用的，主要是解方程(matlab of 60 small programs, it is useful, the main equation is the solution)

该程序能够成功产生2条多径，锐利衰减信道，运行无误(The program can be successfully produced more than two tracks, running correct)
