原创 信号与系统----导论1杂谈为什么要学信号与系统
背景此处讨论以EE相关专业为背景，一般学信号与系统时，你应该已经学了电路原理、模拟电路、数字电路、高等数学、线性代数、概率论与数理统计等。同时还可能在学复分析、偏微分方程或数理方程、电磁场与电磁波、微波与天线、通信原理等等。各个高校安排可能有所差别，但是一般顺序上差不多，但是深度上会差很多，而且侧重也不太一样。强烈建议感兴趣且有精力的同学，不要局限于教材，图书馆就是宝库，图书馆不行，就自己...

Learn PHP 7 Object-Oriented Modular Programming
Learn PHP 7: Object-Oriented Modular Programming using HTML5, CSS3, JavaScript, XML, JSON, and MySQL is intended for use as a beginning level programming book. It is not the goal of this book to cover advanced techniques in the current versions of the PHP programming language. Some knowledge of general programming concepts is expected but no actual programming experience or education is assumed.
All code examples in this book are compatible with PHP 7. Most examples are compatible with PHP 5.6. The newest (as of the publication date) methods (functions) available in PHP have been used to provide
the reader with the most current coding techniques. The examples use core methods provided in the PHP language. PHP includes many additional methods to accomplish similar tasks. The reader may, and should, research additional ways of improving security, performance, and other techniques. It is the goal of this book to prompt users to always consider using the most secure and efficient methods of program development. The code in this book provides some examples of using these techniques. The user should remember that
no program is 100% secure. The programmer can only strive to make an application as secure as possible. It takes a team of developers, network personnel, security administrators, data center personnel, and others working together to provide the safest environment.
