ECG signal simulation by Matlab using m-code

这是关于mathlab软件使用的一些入门级教程，对mathlab初学者有一定的帮助。(This is an entry-level course about the using of mathlab , it may have some help for mathlab beginners .)

自编图像退化程序，包括图像的模糊与加噪，解释详细，希望对学习图像复原的朋友有所帮助。(Self image degradation process, including blur and add noise, a more detailed explanation, I hope the friends of learning image restoration help.)

Studying Sound Frequency

假定半波长间隔均匀分布线列布阵的阵元数N=16，若入射平面波为f=62.5Hz的正弦信号，信号持续时间为0.4s， 系统采样频率 =1 KHz,阵列加权为均匀加权，分别给出 a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时，指向90度的波束形成器的输出序列； b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives: a) 90 degree response when incidence angles are: 0: 10: 100 degrees b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )

两个重要文件： 1、Rayleigh_Doppler_singlePath.m 产生单径Rayleigh衰落，采用了6种方法并进行了比较，推荐使用第6种方法； 2、Rayleigh_Doppler_multiPath.m 根据多条径的延时和强度，产生频率选择性衰落； 在单径和多径两个程序中，均提供了其功率谱的输出代码； (Two important documents: 1, Rayleigh_Doppler_singlePath.m to generate a single path Rayleigh fading, using six kinds of ways and compared, 6 recommended methods 2, Rayleigh_Doppler_multiPath.m under a number of path delay and intensity, resulting in frequency selective fading in both single path and multi-path process, provide the output of its power spectrum code )

这个程序是理论和仿真呼叫阻塞率的对比!希望大家能多多交流学习!(this procedure is the theoretical simulation and call blocking rate contrast! Hope that we can conduct more exchanges learning!)

采用buck-boost双向DC-DC变换，实现脉冲充放电，输入Ts=1e-4 (The buck-boost bidirectional DC-DC conversion, pulse charge and discharge the input Ts, = 1e-4 )
