介绍了开关电源的基础知识, DC-DC 变换器的3 种基本电路: 降压电路、升压电路和极性反转电路的结 构和工作原理。设计了以通用DC-DC 变换器控制芯片MC34063A 及其外围电路为基础的小功率DC-DC 变换 器的实验装置。提出了实验中应该注意和研究的问题。对于学生认识和应用DC-DC 变换器有很大的帮助-Introduces the basics of the switching power supply, three kinds of DC-DC converter circ

This paper proposes a hybrid architecture algorithm for fast computation of DCT and DFT via recursive factorization. Recursive factorization of DCT-II and DFT transform matrix leads to a similar architectural structure so that common architec

使用Dreamweaver开发的图形切换源码，鼠标点一下数字会变换到另一张图片，不点就会自动换。-Using Dreamweaver development of graphics switching source, mouse click number will transform to the other a picture, not automatically change.
