语音信号的几种概率密度函数，包括高斯模型、Laplace模型和广义高斯模型。(Several probability density function of the speech signal, including the Gaussian model, the Laplace model and the generalized Gaussian model.)

这个是全部的matlab下的时频分布在故障诊断中的运用的代码(This is all the Matlab under the time-frequency distribution in fault diagnosis on the use of code)

一个GUI界面，包括图像反转、对数和幂次变换、直方图均衡化等等(A GUI interface, including image inversion, logarithmic and power transformations, histogram equalization, etc.)

此函数介绍了非线性函数在MATLAB理是通过什么函数进行拟合的(This function describes the nonlinear function in the MATLAB function through what management is fitting)

用灰度线性变化的方法进行图像增强，包含代码及代码注释(Using grayscales linear method of image enhancement, contain code and code comments)

语音增强程序 可以作为参考使用,区分清辅音和拙辅音!!!(Speech enhancement procedures can be used as reference!!!)

1.题目：数字滤波器的设计与应用 2.设计要求：利用 Matlab 软件,以复合信号分离为例,对 “数字信号处理” 课程中 的谱分析 、数字滤波器设计和信号滤波这三个过程进行了仿真实现,给出了仿真结果。 3.具体步骤： （1）构造原始信号s(t) （2）画出s(t)的频谱 （3）设计ellipse数字滤波器(IIR)，包括低通，带通，带通，并显示幅频特性 （4）用得到的滤波器进行滤波，分离出三路信号，观察时域波形和幅频特性 （5）用三路信号s1,s2,s3尝试重新合成原始信号 4.问题：为什么重新合成的信号和原信号不相等呢？谁能解释一下？谢谢,QQ:664519036( 1. Title: Digital Filter Design and Application 2. Design requirements: use of Matlab software to composite signal separation, for example, on "Digital Signal Processing" course Of the spectral analysis, digital filter design and signal filtering process carried out three Simulation, the simulation results. 3. Concrete steps: (1) construct the original signal s (t) (2) Draw s (t) of the spectrum (3) design ellipse digital filter (IIR), including low pass, band pass, band pass, and shows amplitude-frequency characteristics (4) filtering with a filter obtained by the isolation of three signals, observed time-domain waveform and frequency characteristics (5) with a three-way signal s1, s2, s3 try to re-synthesis of the original signal 4. Question: Why is re-synthesized signal and the original signal is not equal to it? Who can explain? Thank you, QQ: 664519036)
