CABLE

CABLE即为有线电视电缆。CABLE网络是基于有线电视网而组成的网络。CABLE接入,就是基于CATV(HFC)网的网络接入技术,它是近几年随着网络应用的扩大而发展起来的,主要使用有线电视网进行数据传输。
  • IEEE1394A-2000

    IEEE1394分为两种传输方式:Backplane模式和CABLE模式。Backplane模式最小的速率也比USB1.1最高速率高,分别为12.5 Mbps 、25 Mbps、50 Mbps,可以用于多数的高带宽应用。CABLE模式是速度非常快的模式,分为100 Mbps、200 Mbps和400 Mbps几种,在200Mbps下可以传输不经压缩的高质量数据电影。 IEEE 1394a-2000(FireWire 400)和IEEE 1394-1995几乎相同,改良数个地方之后制定的新规格。为了和后述的IEEE 1394b分别,因此称为"FireWire 400"。在工业上使用的时候,有时就单纯称呼为".a"。

  • AD810

    PRODUCT DESCRIPTION The AD810 is a composite and HDTV compatible, current feedback, video operational amplifier, ideal for use in systems such as multimedia, digital tape recorders and video cameras. The 0.1 dB flatness specification at bandwidth of 30 MHz (G = +2) and the differential gain and phase of 0.02% and 0.04° (NTSC) make the AD810 ideal for any broadcast quality video system. All these specifications are under load conditions of 150 Ω (one 75 Ω back terminated CABLE). The AD810 is ideal for power sensitive applications such as video cameras, offering a low power supply current of 8.0 mA max. The disable feature reduces the power supply current to only 2.1 mA, while the amplifier is not in use, to conserve power. Furthermore the AD810 is specified over a power supply range of ±5 V to ±15 V.

  • 3G,+4G+and+Beyond–BRINGING NETWORKS

    In recent years, cellular voice networks have transformed into powerful packet-switched access networks for both voice communication and Internet access. Evolving Universal Mobile Telecommunication System (UMTS) networks and first Long Term Evolution (LTE) installations now deliver bandwidths of several megabits per second to individual users, and mobile access to the Internet from handheld devices and notebooks is no longer perceived as slower than a Digital Subscriber Line (DSL) or CABLE connection. Bandwidth and capacity demands, however, keep rising because of the increasing number of people using the networks and because of bandwidth-intensive applications such as video streaming. Thus, network manufacturers and network operators need to find ways to continuously increase the capacity and performance of their cellular networks while reducing the cost.

  • Emerging Technologies in Wireless LANs Theory

    Wireless Fidelity (Wi-Fi) networks have become mainstream over the last few years. What started out as CABLE replacement for static desktops in indoor networks has been extended to fully mobile broadband applications involving moving vehicles, high-speed trains, and even airplanes.

  • Fundamentals+of+Digital+Communication

    The field of digital communication has evolved rapidly in the past few decades, with commercial applications proliferating in wireline communi- cation networks (e.g., digital subscriber loop, CABLE, fiber optics), wireless communication (e.g., cell phones and wireless local area networks), and stor- age media (e.g., compact discs, hard drives). The typical undergraduate and graduate student is drawn to the field because of these applications, but is often intimidated by the mathematical background necessary to understand communication theory.

  • Modeling+and+Analysis+of+Telecommunications

    The insinuation of telecommunications into the daily fabric of our lives has been arguably the most important and surprising development of the last 25 years. Before this revolution, telephone service and its place in our lives had been largely stable for more than a generation. The growth was, so to speak, lateral, as the global reach of telecommunications extended and more people got telephone service. The distinction between oversea and domestic calls blurred with the advances in switching and transmission, undersea CABLE, and communication satellites. Traffic on the network remained overwhelmingly voice, largely in analog format with facsimile (Fax) beginning to make inroads.

  • Understanding+Telecommunications+Business

    The dictionary definition of telecommunications is ‘communication over long distance by CABLE, telegraph, telephone or broadcasting’, but since its initiation over 100yearsagothingshavemovedrapidly.Telecommunicationsisnowaverycomplex industrywithmanydifferentpressures,operatinginahighlydynamic environment.It is best viewed as part of a wider industry known as information and communication technology (ICT). The purpose of this chapter is to explain where telecommunication fits in, to highlight some of the complexities – hopefully to simplify them – and to position the industry in today’s dynamic business environment.

  • Xilinx开发板初学者问题总结

    1. Impact 软件或者ISE 软件停止工作系统升级了Win10,安装ISE14.7 后发现了一些问题, 影响了软件的使用, 非常不爽,检索了网上的解决信息,尝试了一些方法,基本解决了问题,先总结如下:1.ISE (64bit )软件在进行打开文件或文件夹操作时,软件出现闪退的现象, ISE(32bit )没有这个问题。解决方法:找到程序安装路径下的这两个文件夹X:\Xilinx\14.7\ISE_DS\ISE\lib\nt64X:\Xilinx\14.7\ISE_DS\common\lib\nt64首先在第一个文件夹中,重命名libPortability.dll 为libPortability.dll.orig ,然后复制libPortabilityNOSH.dll 的一个副本并重命名为libPortability.dll ,这样你就又有一个libPortability.dll 文件了;然后在第二个文件夹,将之前得到的新的libPortability.dll 覆盖到这个文件夹中。EDK没有libPortabilityNOSH.dll 这个文件,把ISE 的复制过来就可以了2.Xilinx 下载电缆找不到的问题原先在Win7 下电缆去驱动是自己安装的, 没有这个烦恼,Win10下虽然也会自己安装,但是在iMpact 或ChipScope 下面会提示找不到电缆错误。解决方法:进入这个目录: X:\Xilinx\14.7\ISE_DS\common\bin\nt64双击install_drivers.exe ,如果电脑有连接CABLE 请按照提示断开连接,安装完毕后就可以正常使用了。解决办法: 因为ISE 64位软件和win10/win8 系统不太兼容, 需要打开ISE 32位软件,再打开ISE开发环境下的Impact 工具。3. ISE 安装后无法打开有安装完 ISE软件后,打开时显示Clip host, 如下图。
