  • CC1110:RF 片上系统解决方案

    The CC1101 is a low-cost sub- 1 GHztransceiver designed for very low-powerwireless applications. The circuit is mainlyintended for the ISM (Industrial, Scientific andMedical) and SRD (Short Range Device)frequency bands at 315, 433, 868, and 915MHz, but can easily be programmed foroperation at other frequencies in the 300-348MHz, 387-464 MHz and 779-928 MHz bands.CC1101 is an improved and code compatibleversion of the CC1100 RF transceiver. Themain improvements on the CC1101 include:

  • 基于微带结构双左手频带左手材料的研究

    混合左右手材料的两个通带分别出现在2.5 GHz和6 GHz处。通过仿真获得S11、S21和色散曲线,从理论上验证了左手特性的存在。具有双左手频带的左手材料将在未来四频器件中得到广泛应用。

  • Proteus教程中涉及的基本概念

      基本的编辑工具(GENERAL EDITING FACILITIES)   对象放置(Object Placement)   ISIS支持多种类型的对象,每一类型对象的具体作用和功能将在下一章给出。虽然类型不同,但放置对象的基本步骤都是一样的。   放置对象的步骤如下(To place an object:)   1.根据对象的类别在工具箱选择相应模式的图标(mode icon)。   2. Select the sub-mode icon for the specific type of object.   2、根据对象的具体类型选择子模式图标(sub-mode icon)。   3、如果对象类型是元件、端点、管脚、图形、符号或标记,从选择器里(selector)选择你想要的对象的名字。对于元件、端点、管脚和符号,可能首先需要从库中调出。   4、如果对象是有方向的,将会在预览窗口显示出来,你可以通过点击旋转和镜象图标来调整对象的朝向。   5、最后,指向编辑窗口并点击鼠标左键放置对象。对于不同的对象,确切的步骤可能略有不同,但你会发现和其它的图形编辑软件是类似的,而且很直观。   选中对象(Tagging an Object)   用鼠标指向对象并点击右键可以选中该对象。该操作选中对象并使其高亮显示,然后可以进行编辑。

  • US Navy VHDL Modelling Guide

      This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) project. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL Data Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production data and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP project, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.

  • 如果已经安装好了vobsub

    如果已经安装好了vobsub,就可以运用vobsub里面带的字幕提取工具vsrip提取字幕。 打开VobSub程序组,运行vobsub.configure,点击Open来打开vts_01_0.ifo文件(此文件已经拷贝到硬盘上,无需从光盘上找),选定放置字幕文件的子目录,点击确定.提取完成之后会生成Vts_01_0.sub和vts_01_0.idx两个字幕文件,若按照DVDrip的做法是在最终视频文件生成之后,将字幕文件更名并与主体一致,但在此这个步骤被提前了,因为real格式文件的字幕是嵌入在画面那的.我们需要做的是将vts_01_0.idx和vts_01_0.sub更名为vts_01_1.idx和vts_01_1.sub,与vts_01_1.vob同名.这样才能进行制作时被vobsub自动调用同步嵌入字幕

    VHDL 关于2DFFT设计程序 u scinode1 ∼ scinode9.vhd: Every SCI node RTL vhdl code. The details can be seen in the following section. u 2dfft.vhd: The top module includes these scinodes and form a 3x3 SCI Torus network, and it support these sub-modules scinode1∼ scinode9 reset and clk and global_cnt signals to synchronous the sub-modules to simplify the overall design. u proj2.wfc: VSS simulation result that is the same as the ModelSim simulation result. u Pro2_2.wfc: VSS simulation result of another test pattern can’t cause overflow situation.

    DIGITAL IMAGERY is pervasive in our world today. Consequently, standards for the efficient representation and interchange of digital images are essential. To date, some of the most successful still image compression standards have resulted from the ongoing work of the Joint Photographic Experts Group (JPEG). This group operates under the auspices of Joint Technical Committee 1, Subcommittee 29, Working Group 1 (JTC 1/SC 29/WG 1), a collaborative effort between the International Organization for Standardization (ISO) and International Telecommunication Union Standardization Sector (ITUT). Both the JPEG [1–3] and JPEG-LS [4–6] standards were born from the work of the JPEG committee. For the last few years, the JPEG committee has been working towards the establishment of a new standard known as JPEG 2000 (i.e., ISO/IEC 15444). The fruits of these labors are now coming to bear, as JPEG-2000 Part 1 (i.e., ISO/IEC 15444-1 [7]) has recently been approved as a new international standard.
