矢量网络分析仪的基本原理

利用ENVI波段运算功能和IDL运算符进行运算的示例(Using ENVI band math functions and operators for IDL operation example)

虚拟光驱是一种模拟（CD/DVD-ROM)工作的工具软件，可以生成和你电脑上所安装的光驱功能一模一样的光盘镜像，一般光驱能做的事虚拟光驱一样可以做到， 工作原理是先虚拟出一部或多部虚拟光驱后，将光盘上的应用软件，镜像存放在硬盘上，并生成一个虚拟光驱的镜像文件，然后就可以将此镜像文件放入虚拟光驱中来使用，所以当您日后要启动此应用程序时，不必将光盘放在光驱中，也就无需等待光驱的缓慢启动，只需要在插入图标上轻按一下，虚拟光盘立即装入虚拟光驱中运行，快速又方便(Virtual drives is a simulation (CD/dvd-rom) working tool software, can generate and installed on your computer to get rid of function exactly the same CD mirror, general cd-rom can do virtual drives as can be done, working principle is first virtual out a or more after the virtual drives, the application of the software will be CD, mirror stored in hard drive, and to create a virtual drives the image files, and then you can put the image files into virtual drives to use in the future, so when you want to start the application, not on cd-rom, CD will also need not wait for cd-rom, only need to slow start in insert icon click, virtual CD light immediately into virtual drives, fast and convenient in operation )

2fsk的调制与解调，基于sinmulink与systemview的仿真(2fsk modulation and demodulation, and systemview simulation based sinmulink)

实现PI+重复控制的有源电力滤波器（APF）(An active power filter (APF) that using PI+ repetitive control)

资源描述spi 测试接口，用来读写寄存器，经过实际测试，可以正确读写。

DLP背投技术资料，针对现有的DLP技术进行了详细的讲解，对初次接触DLP技术的人来说非常有帮助。(DLP rear projection technology information for an existing DLP technology for a detailed explanation of the initial contact with DLP technology for people who are very helpful.)

说明：  包含主板，驱动板，运放等所需全部板工程文件(Contains all board engineering files required for motherboard, driver board, op amp, etc.)

说明：  通过IO口控制两路24V电压输出，一路24V转两路24V(Two 24V voltage outputs are controlled by IO port, one 24V is converted to two 24V.)

提供一个基于瑞昱RTL8382L24口交换芯片的24口+2光口的千兆交换参考设计。包括基于Cadence平台设计的原理图、PCB和RTL8382L、RTL8281B的技术手册。(A Gigabit switching reference design based on 24 + 2 optical ports of Ruiyu RTL8382L24 switch chip is provided. Including the schematic design based on the Cardence platform, PCB and RTL8382L, RTL8281B technical manual.)

比较接近实际硬件的IGBT 模型，可以做个参考(IGBT model approaching to actual hardware )
