Dynamic Time Warping Script

对语音信号假入宽带高斯白噪声并用小波降噪(add white noise to signal and decrease it with wavelet)

power flow by newton-aphson method

lpc线性预测编码，合成与分析析，在matlab中实现-lpc (lpc linear predictive coding, synthesis and analysis of the analysis, in-lpc in Matlab)

用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(fft analysis,plot rms spectrum,power density spectrum, etc.)

说明：  利用matlab，实现插值滤波器的设计 有需要的朋友可以(Using matlab, realize the design of interpolation filters can have a friend in need)

说明：  基于matlab的GUI界面设计的成绩管理系统，可以直接用！(Based on the matlab GUI interface design of the performance management system )

说明：  针对给定信号采用不同的现代功率谱估计方法进行功率谱估计，并附有PPT讲义！(For a given signal using a different method of power spectrum estimation of modern power spectrum estimation, along with PPT handouts!)

说明：  在MATLAB上所使用的PCA程序，主要應用於過濾相對較不重要的特徵值(dimension)，例如在三度空間的某些點具有(x,y,z)值，因為這些點有共同的一個持徵，就是z值相對於x,y值來得小很多(不明顯)，所以就以X,Y軸來表示這些點。此時就達成去除掉z的特徵值(dimension)。 (MATLAB used in the PCA procedure, mainly used in filtering relatively unimportant eigenvalue (dimension), for example, in some points with three-dimensional (x, y, z) values, because these points have a common one sign holders, that is, z values compared with the x, y values much smaller than (not obvious), so on to X, Y axis to express these points. Reached at this time to get rid of z eigenvalues (dimension).)
