Duffing系统的时域谱图和相空间轨迹绘制，能够帮助初学者很好的理解典型非线性特征(duffing equation Phase plane trajectory)

电话拨号音的合成与识别 基于对电话通信系统中拨号音合成与识别的仿真实现，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。使其对电话通信系统拨号音的合成与识别有个基本的了解。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程。(Synthesis and recognition telephone dial tone Based on telephone communication system dial tone Simulation synthesis and recognition, mainly related to the basic principles of the main methods telephone dial tone synthesis and recognition, using MATLAB software and the FFT algorithm for synthesis and recognition telephone communication system dial tone. And further use of MATLAB graphical user interface is simple and intuitive GUI making analog interface. Synthesis and recognition make telephone communication system dial tone have a basic understanding. Can be different the fundamental frequency of matrix synthesis 0 9 dial tone different keys, and can be correctly identify different dial tone, dial tone achieved by the parsed telephone number of processes.)
