说明：  录制一段个人的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用双线性变换法和窗函数法设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a personal voice signal, and recording the signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum for a given filter performance, the bilinear transformation and design of filter window functions and draw the frequency response filter then filter of their own design collection of the signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, analysis of signal changes playback audio signals Finally, a signal processing system interface design.)

说明：  Levenberg-Marquardt算法 使用Levenberg-Marquardt算法来最小化(Levenberg-Marquardt algorithm using the Levenberg-Marquardt algorithm to minimize the model)

Matlab 降噪程序，使用LMS算法去除噪声，在一段添加噪音的音频文件中滤除噪声！(Matlab Noise reduction LMS)

说明：  用matlab自带的GUI界面设计了一个成绩管理界面，可进行成绩的载入、查询、绘图、求平均分和存储！可直接用！ (Matlab GUI interface that comes with the design of a performance management interface, the results of the load, query, plot, find the average and store! Can be used directly!)

从变量可见性角度分析，Matlab程序运行过程中（以下不特别说明都是指在Matlab程序中），不同形式的变量可见范围源于于面向对象编程的概念.(variables can be seen from the point of view of analysis, Matlab procedures in the process (not refer specifically explain procedures in Matlab), different forms of variable can be seen in the area stems from the object-oriented programming concepts.)
