In mathematics and, in particular, functional analysis, convolution is a mathematical operation on two functions f and g, producing a third function that is typically viewed as a modified version of one of the original functions. Convolution is similar to cross-correlation. (This files includes matlab source file and report file)

线性调频信号的产生线性调频信号的产生线性调频信号的产生(The generation of linear frequency modulation signal )

说明：  用于检测微弱信号的Duffing系统，这是我的毕业设计一部分，因为我做的时候也曾求取过很多资料，但是并没有找到，因此在我完成之后，上传这个代码，希望这个能帮助别人。 里面还有后续做的GUI界面实现的Duffing振子检测功能，可检测信号幅值和频率。(The Duffing system for detecting weak signals, this is part of my graduation project, because I also asked for a lot of information when I did it, but it was not found, so after I finished, upload this code, I hope this can help others.)

“基于MATLAB的系统分析与设计—信号处理”一书是一本极好的的书，对初学信号处理的非常值得一读。该书针对应用广泛的的号处理领域，简要介绍了信号处理的基本概念和基本方法，详细介绍了由MATLAB提供的信号处理工具箱函数的用法指南，最后以大量的应用示例，说明MATLAB进行信号处理系统分析与设计方法。( Based on MATLAB-Analysis and Design- Signal Processing, a book is an excellent book, for beginner signal processing is very worth reading. The book aimed at a wide range of applications to deal with the No. field, briefly introduced the basic concepts of signal processing and basic methods, detailed information provided by the MATLAB Signal Processing Toolbox function usage guide, and finally to a large number of application examples MATLAB signal dealing with system analysis and design methods.)
