Time-Frequency Signal Analysis and Processing-A Comprehensive Reference，时频分析的经典教材，第二版，英文高清，带目录标签

最近有个项目需要用到网络获取时间，C++来实现，并用年月日显示出来，大量百度资料，都是需要整理下才能使用，我直接做个笔记，下载下来就可以使用，简单方便快捷，并附带WS2_32.lib库文件，不懂的直接评论留言

Multivariate time series analysis considers simultaneously multiple time series. It is a branch of multivariate statistical analysis but deals specifically with dependent data. It is, in general, much more complicated than the univariate time series analysis, especially when the number of series considered is large. We study this more complicated statistical analysis in this book because in real life decisions often involve multiple inter-related factors or variables. Understanding the relationships between those factors and providing accurate predictions of those variables are valuable in decision making. The objectives of multivariate time series analysis thus include 1. To study the dynamic relationships between variables 2. To improve the accuracy of prediction

学习完GUI之后，用java语言编写实现简单计时器功能，GUI做图形化界面，新手可以参考，不惜勿喷。

时频分析时频分析（JTFA）即时频联合域分析（Joint Time-Frequency Analysis）的简称，作为分析时变非平稳信号的有力工具，成为现代信号处理研究的一个热点，它作为一种新兴的信号处理方法，近年来受到越来越多的重视。时频分析方法提供了时间域与频率域的联合分布信息，清楚地描述了信号频率随时间变化的关系。
