教程资料 XAPP1065 - 利用Spartan-6 FPGA设计扩频时钟发生器
 
Consumer display applications commonly use high-speed LVDS interfaces to transfer videodata. Spread-spectrum clocking can be used to address electromagnetic compatibility (EMC)issues within these consumer devices. This application note uses Spartan®-6 FPGAs togenerate spread-spectrum ...
通信网络 tcp ip协议详解 中文版PDF
很多不同的厂家生产各种型号的计算机，它们运行完全不同的操作系统，但TCP.IP协议族允许它们互相进行通信。这一点很让人感到吃惊，因为它的作用已远远超出了起初的设想。T C P / I P起源于6 0年代末美国政府资助的一个分组交换网络研究项目，到9 0年代已发展成为计算机之间最常应用的组网形式。它是一个真正的开放系统， ...
通信网络 基于以太网的虚拟示波器设计
为提升虚拟仪器传输速率与实时性能，扩展监测范围，在VC的软件平台上设计了一种全功能虚拟示波器。与传统虚拟示波器相比，该系统采用嵌入式系统完成信号采集，采用工业以太网为传输介质，通过线性插值算法和多线程编程思想，实现波形显示、参数计算、频谱分析以及波形存储及回放功能。实验结果表明，该虚拟示波器可以实现20 ...
通信网络 基于Simulink的数据链系统仿真及性能分析
1扩频系统原理 扩展频谱(Spread Spectrum)技术是将基带信号的频谱扩展至较宽的频带上，然后再进行传输的一种宽带信号传输方法，它将要发送的制导信息或导弹回传信息用伪随机序列扩展到一个合适的频带上，即将原始信息的能量在频带上进行扩展，从而降低了信号被发现的危险，增加了敌方干扰的难度(需要干扰的范围变大 ...
