傅里叶变换和傅里叶变换的性质,周期信号和非周期信号的频谱分析,卷积和卷积定理,抽样信号的傅里叶变换和抽样定理,相关、能量谱和功率谱.(Fourier transform and Fourier transform nature, the cycle-cycle signal and the signal spectrum analysis, Convolution and convolution theorem, the sampling signal to the Fourier transform and sampling theorem related to the energy spectrum and the power spectrum.)

高阶累积量，用于信号的调制识别，性能较好(high order cumulant,used to AMC.)

matlab 软件Allan 方差分析程序(A matlab program used for Allan covarice analysis)

Heat Equation with variable coefficients. Solution of the heat equation using point gauss method

Tranformasi wavelet merupakan perbaikan dari transformasi Fourier. Transformasi Fourier hanya dapat menangkap informasi apakahsuatu sinyal memiliki frekuensi tertentu ataukah tidak, tapi tidak dapat menangkap dimana frekuensi itu terjadi. Jika Transformasi Fourier hanya memberikan informasi tentang frekuensisuatu sinyal, maka transformasi wavelet memberikan informasi tentang kombinasi skala dan frekuensi

低通滤波器实现滤波白噪声，产生一定宽度的白噪声(noise filter)

说明：  LMS自适应滤波器是使滤波器的输出信号与期望响应之间的误差的均方值为最小，因此称为最小均方（LMS）自适应滤波器。(LMS adaptive filter is to minimize the mean square value of the error between the output signal of the filter and the expected response, so it is called LMS adaptive filter.)

图片，很经常用的一副matlab里面的图片(Picture, it is often used inside a pair of matlab Photos)

说明：  噪声中非平稳信号的频谱分析，基于MATLAB，实验报告一份(Nonstationary noise frequency spectrum analysis, based on MATLAB, a lab report)
