光耦合电路求好心人帮忙
求大神帮我看一下为什么输入交流信号输出是直流呢光耦合电路求好心人帮忙把楼主的问题顶起了,,跟光耦的特性参数有关,LED的驱动电流以及光电管侧的负载电阻取值,不同型号的光耦就会不一样,而且这个电路无法仿真。最后一级感觉是TIA跨阻放大器。。。前面具体什么没看出来。。。。。求教建议还是实际去大电路调试比较好...

驻波比分析模块在漏缆监测系统中的应用
在基站与移动站之间的通讯,通常是依靠无线电传送。目前通讯业的不断发展越来越要求基站与移动站之间随时随地能接通,甚至要求在隧道中也是如此。然而在隧道中,移动通信用的电磁波传播效果不佳。隧道中利用天线传输通常也很困难,所以关于漏缆的研究也应运而生。无线电地下传输有着极其广泛的用途,例如:用于建筑物内、隧道内及地铁的移动通信(GSM,PCN/PCS,DECT)用于地下建筑的通讯,例如停车场、地下室及矿井公路隧道内FM波段(88-108MHz)信息的发送公路隧道内无线报...

关于spi 的问题,请各位大大指导下
我是嵌入式新手,现在手头有一块s3c2410的板子,老师要我用spi编wifi程序,看说明上没有关于spi的资料,用baidu搜出来知道了spi是一个通信协议,好像和单片机的汇编语言有关的,但是我只会用c语言,按照我们老师的说法好像还要移植到linux上去,我现在没有说明头绪啊,不知道要从哪里开始,大家有么有类似的程序或者资料给我参考下啊,据说貌似好像很简单的,只要几句简单的话就能实现这个功能呢关于spi的问题,请各位大大指导下SPI是同步串行口呵呵,一般的芯片应该带有这个基本的通信口...
