对输入信号进行傅立叶变换，并画出单边频谱图(Of the input signal Fourier transform, and draw a unilateral Spectrum)

这个程序可以修复因噪声/噪音干扰或者因抖动产生的失真的图像，Inverse滤波器, Wiener滤波器和Lucy-Richardson滤波器被使用到，同时代码还使用了光学流线分析，估计模糊的长度和角度。(This program can recover from noise/noise or distortion due to jitter generated images, Inverse filter, Wiener filter and the Lucy-Richardson filter were used, while the code also uses optical flow line analysis, estimated the length and fuzzy angle.)

自己写的提取音频信号mfcc参数的算法，用matlab实现，欢迎大家参考(Write their own audio signal MFCC extraction algorithm parameters, using matlab to achieve, welcome to the reference)

用matlab实现股票分析中的WRI指标，可用于例程学习(Stock analysis using matlab realize the WRI indicators, can be used for routine learning)

利用自适应陷波器来消除通信系统中的工频干扰。重点从LMS算法的步长因子、信号与干扰的频率差、参考输入的幅值和相位等几个方面讨论单频陷波器的滤波效果。另外，还以双频为例，讨论了多频级联型陷波器的特性，证实了经过两次滤波后，信号可被真实的恢复出来，且误差收敛趋于稳定。(The use of adaptive notch filter to eliminate the communication system frequency interference. LMS algorithms focus from step factor, the frequency difference signal and interference, refer to the input amplitude and phase of discussions on several aspects of single-frequency notch filter of the filtering effect. In addition, in order to dual-band, for example, discussed the multi-frequency cascade notch filter characteristics, confirmed the filtered twice, the signal can be restored out of true, and the error convergence stable.)
