1、观察采样引起的混叠。 2、判别离散时间系统的时不变性。 3、利用卷积计算信号通过FIR滤波器的输出，并观察输出信号的input-on暂态、input-off暂态和稳态阶段。 (One to observe the sampling due to aliasing. 2, determine the time invariant discrete-time systems. 3, the use of convolution calculation of the signal through the FIR filter output, and observe the output signal of the input-on transient, input-off transient and steady-state phase.)

Function to perform Principle Component Analysis over a set of training vectors passed as a concatenated matrix. Usage:- [V,D,M] = pca(X,n) [V,D] = pca(X,aM,n) where:- <input> X = concatenated set of column vectors aM = assume that the mean is aM n = number of principal components to extract (optional) <output> V = ensemble of column eigen-vectors D = vector of eigen-values M = mean of X (optional)

说明：  进行两个数据文件的FFT对比分析，可以设置分析参数，比较简单，matlab7运行通过(Two data files for comparative analysis of the FFT, you can set up analysis parameters, relatively simple, matlab7 run through)

说明：  Logistic混沌随机序列的MATLAB产生源程序(Logistic chaotic random sequences generated source MATLAB)

通过一个单一的合成器实现众多乐器和音效的控制。我们要做的工作就是通过一定的方法合成一段不少于30秒的音乐，并流畅播放。设计中主要采用音调幅度调制的方式再现乐曲。(A number of musical instruments and sound control through a single synthesizer. We work to be done is through the method of synthesis of a period of not less than 30 seconds of music, and smooth playback.The design of the main tone amplitude modulation reproduction of music. )

Weighted covariance function. Allows to give more weight on recent observations.
