介绍了傅立叶变换的基本原理，并给出了傅立叶变换的c语言实现(Introduced the basic principles of Fourier transform, and gives the Fourier transform of c language)

该程序是用VC++编写的程序，是关于SQL语句中设置多个字符串检索条件方面的，成品语句，可以独立运行，参考价值较高。(The program is VC++ Preparation procedures on the SQL statement string to set up a number of search terms, finished statement, can run independently, a high reference value.)

鬼影DDOS集群发包源码，分为客户端和服务端完整源码(Ghost DDOS cluster source code, divided into client and server complete source code)

详细讲解了操作系统原理及实现方式，通过实例一步步引导读者用汇编语言和c语言编写操作系统框架(Detailed account of the operating system theory and implementation, guiding the reader step by step through examples written in the framework of the operating system in assembly language and c language)

说明：  在基于脉冲的UWB系统中，采用瑞克接收机合并多径信号能量并进行相干检测，信道估计问题即估计多径信号的到达时间和幅度。在基于OFDM的UWB系统中，接收机根据信道频域响应对每个子信道进行频域均衡后进行相干检测，信道估计问题即估计信道频域响应。(Pulse-based UWB systems, rake receivers using the combined multipath signal energy and coherent detection, channel estimation problem that is estimated multipath signal arrival time and amplitude. OFDM-based UWB system, the receiver under the channel frequency response of each subchannel to frequency domain equalization after coherent detection, channel estimation problem that is estimated channel frequency response.)

说明：  用PIC做的一个学习型无线遥控开关的代码 这是网上找来的，用pic12f6系列芯片，可以控制二路开关(PIC to do with a wireless remote control switch to learn the code this is brought online, and pic12f6 series of chips used to control switches Rd)

基于MSP430G2553的湿度 基于单片机的空气湿度检测系统 设计与实现(Air humidity detection system based on MSP430G2553 based on single chip microcomputer Design and Implementation)

设计题目:读写磁盘文件 设计要求：能正确执行对硬盘文件的读写 设计应用：熟练基本的汇编编程，为后来编程打基础。 设计思路：反复利用DOS系统功能调用，进行操作。(design topics : read and write disk file design requirements : the correct implementation of the document literacy drive design applications : a compilation of basic proficiency in programming, laying the foundation for the subsequent programming. Design Idea : repeated use DOS system function calls, to operate.)

定时器每100us中断一次，在中断服务程序中,对中断次数进行计数，100us计数10000次就是1秒。然后再对秒计数得到分和小时值，并送入显示缓冲区。(Timer interrupt every 100us, in the interrupt service routine, the interrupt number of counts, 100us count is 1 second 10000. Then seconds count the minutes and hours values 椠渀琀漀 the display buffer.)

C语言是一种计算机程序设计语言,它既具有高级语言的特点,又具有汇编语言的特点。它的功能性非常强大,目前是各高校的一门必修课。并且市场上许多软件也是基于C语言的平台而产生的,所以C语言在大学中的教学也称得上是"不遗余力"。但是近些年很多的学生普遍反映C语言晦涩难懂,不容易学透,非常努力的学最后却得不能心满意足,课程过后一无所获,甚至一个小小的程序都写不出来,于是针对这些情况就做出一些初步的分析,并且从C语言编程技巧上提出相关的改善对策。 (C language is a computer programming language, both with advanced language features, but also has characteristics of assembly language. Its function is very powerful, is now a required course in colleges and universities. And also a lot of software on the market based on the C language, platform and produce, so C language teaching at the university is also described as a "spare no effort." But in recent years, a lot of students generally reflect the C language obscure, not easy to learn thoroughly, very hard to learn, but finally could not have satisfied the course after nothing, even a small program that can not write, so for these situations to to make some preliminary analysis, and from the C programming language skills relevant improvement measures put forward.)
