pixel by pixel feature extraction

(MATLAB) On the companion website, you will find in the directory Chap exercises/chapter3 a workspace ex3M2.mat. In this workspace, you will find waveforms of the words “we” and “be” (at 10000 samples/s) in the array we be 10k. The waveforms and a spectrogram of the waveforms are shownin Figure 3.33. To display the spectrogram andwaveform, use the function specgram ex3p19.m also in Chap exercises/chapter3. To listen to the waveform, use the MATLAB function sound.m.

说明：  我最近用MATLAB做的语音处理实验，含有3种处理方式，希望对大家有帮助。(I have recently done with MATLAB voice processing experiments, containing three kinds of approach, I hope all of you help.)

Music algorithm of uniform linear array

一些典型的DSP程序，对初学者比较有帮助，主要结合Digital Signal Processing——A Computer-based（电子工业出版社）一书课后题目编写。 (Some typical DSP program, the more help for beginners, mainly with Digital Signal Processing——A Computer-based. )

正弦函数与余弦函数的线性组合 变精度数是用确切的有理表示存在的一个小数点。利用变精度而合理的算法，创建变量使用vpa功能。(This example feedforward utilization 2/3 convolutional encoder drawing. Describes how to determine the coded block parameters. This example also illustrates the use of the calculation error block reception delay.)

该程序是一个振荡相位噪声模型。相位噪声是衡量频率标准源(高稳晶振、原子频标等)频稳质量的重要指标，随着频标源性能的不断改善，相应噪声量值越来越小，因而对相位噪声谱的测量要求也越来越高。(The program is a model of phase noise oscillator. Phase noise is a measure of frequency standard source (high stability crystal oscillator, atomic frequency standard, etc.) an important indicator of the quality of the frequency stability, with the frequency standard source performance continues to improve, the corresponding noise value smaller, and thus the phase noise spectrum of the measurement requirements higher and higher.)

给出了一种新的自适应非线性滤波历程，该方法计算量小而且使用方便(Presents a new adaptive nonlinear filtering process, the method is small and easy to use)
