This book is about signal processing, which includes processes for synthesizing, transforming, and analyzing signals. It focuses on sound signals, but the same methods apply to other signals, like electronic signals and mechanical vibration.

说明：  基于TOA定位算法的克劳美罗CRLB仿真程序(CRLB simulation program of TOA location algorithm)

本程序描述了pca在人脸识别上的应用。并带有输入输出，可在人脸库上进行试验。(This procedure describes the pca in face recognition applications. And with the input and output can be tested on the face database.)

这是一个三坐标卡尔曼滤波的程序，是对于跟踪定位的内容的，程序比较详细和使用，一定要看哦(This is a 3D Kalman filtering process, which is tracking the content, procedures and the use of more detailed and look at the oh)

这是一个SA求解tsp旅行商的matlab源代码，由m文件构成，可方便大家学习模拟退火算法。(This is a traveling salesman tsp SA for the Matlab source code, document constitute m, can facilitate learning simulated annealing.)

Matlab 计算有限元的一些程序，期望对大家有些帮助！！！！(Matlab finite element calculation of some of the procedures, expectations of you some help! ! ! !)

the matlab code of other form of hill climbing algorithm.

改变图像的灰度级数，通过输入的数值确定灰度级(change degree of gray )

傅 立叶变换是数字信号处理领域一种很重要的算法。要知道傅立叶变换算法的 意义，首先要了解傅立叶原理的意义。傅立叶原理表明：任何连续测量的时序或 信号，都 可以表示为不同频率的正弦波信号的无限叠加。而根据该原理创立的 傅立叶变换算法利用直接测量到的原始信号，以累加方式来计算该信号中不同正 弦波信号的频 率、振幅和相位。 (The goals for the course are to gain a facility with using the Fourier transform, both specific techniques and general principles, and learning to recognize when, why, and how it is used. Together with a great variety, the subject also has a great coherence, and the hope is students come to appreciate both. )

使用四分量高斯包络信号进行时频分析，比较比较STFT、WVD、CWD分辨率和交叉干扰情况，包含仿真代码及Matlab时频分析工具箱。工具箱的使用建议参考《Matlab时频分析技术及其应用-葛哲学》，压缩包中顺便包含了该书的源代码。(The four-component Gaussian envelope signal frequency analysis, comparison compare STFT on WVD, CWD resolution and cross-interference, frequency analysis toolbox contains the simulation code and Matlab. Use the recommended reference toolbox " Matlab frequency analysis technology and its application- Gezhe school" book contains the source code compression package the way.)
