MODEL BASED ALGORITHM FOR SINGULAR POINT DETECTION

FFT 实例 x=0.5*sin(2*pi*15*t)+2*sin(2*pi*40*t)。采样频率fs=100Hz，分别绘制N=128、1024点幅频图(FFT in Matlab example)

大家看看吧，很好的Matlab学习资料(Let everyone take a look at, very good learning materials Matlab)

利用matlab模拟光纤中EH11模的模式分布图。(Using matlab simulation mode fiber EH11 mode maps.)

The Seismic Unix Project is partially supported by the CWP Consortium Project. In the past, the Seismic Unix Project has received partial support from the Gas Research Institute (GRI) and the Society of Exploration Geophysicists Foundation.

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

数字通信系统仿真，用到MATLAB成语言。(digital communication system modulation)

说明：  这是9225的初始化资料，绝对OK,已测试过的，效果非常不错，欢迎大家试用(This is the 9225 initialization information, absolutely OK, have been tested, the effect is very good, welcome trial)
