介绍matlab程序中的傅里叶变换测试语音，测试语音的频谱，并改变采样率和采样点，在测试语音(Matlab program introduces test Fourier transform voice, test speech spectrum, and change the sampling rate and sampling points, the test speech)

关于focus编程的相关学习资料，有详细的说明(Focus programming related learning materials, detailed instructions)

心电信号加入0.5Hz的基线漂移，通过0.5Hz高通滤波器，滤波后的波形与原波形的对比 ，滤波器特性曲线分析；信号加入50Hz工频漂移，通过50Hz陷波器，滤波后的波形与原波形的对比 ，滤波器特性曲线分析(ECG baseline drift by adding 0.5Hz, 0.5Hz through a high-pass filter, filtering of the waveform after the comparison with the original waveform, filter characteristic curve analysis adding 50Hz frequency signal drift, through the 50Hz notch filter, after filtering waveform compared with the original waveform, filter characteristic curve analysis)

主程序为mybss.m和fastica1.m。经过调试能够成功运行，和lmd一起使用效果不错，可以实现各频率的分离。(The main program is mybss.m and fastica1.m. After debugging can be run successfully, and lmd use with good results, the separation can be achieved for each frequency.)

This is a method called Metoda Fibonacci. And with this method you can find the the optimum way.

Speech Synthesis using MATLAB

光通信系统中应用的对于QAM信号就行姐夫用的复数ICA算法，可以解两路信号的串扰，恢复出良好的输入信号(Optical communication system applications for QAM signal on the line with a brother complex ICA algorithm, can solve the crosstalk of the two signals, the input signal is a good resume)

单频干扰陷波器源码。自适应陷波器,与一般陷波器比较，有两大优点：（1）能够自适应地准确跟踪干扰频率。 （2）容易控制带宽.(Single-frequency notch filter interference source. Adaptive Notch Filter, Notch Filter with the general comparison, there are two main advantages: (1) can be adaptively tracking the exact frequency interference. (2) easy to control bandwidth.)
