  • LT5514三阶互调的精确测量

      Accurate measurement of the third order intercept pointfor low distortion IC products such as the LT5514 requirescertain precautions to be observed in the test setup andtesting procedure. The LT5514 linearity performance ishigh enough to push the test equipment and test set-up totheir limits. A method for accurate measurement of thirdorder intermodulation products, IM3, with standard testequipment is outlined below.It is also important to correctly interpret the LT5514specification with respect to ROUT, and the impact ofdemo-board transmission-line termination loss whenevaluating the linearity performance, as explained in theLT5514 Datasheet and in Note 1 of this document.

  • 基于Multisim 10的矩形波信号发生器仿真与实现

    在Multisim 10软件环境下,设计一种由运算放大器构成的精确可控矩形波信号发生器,结合系统电路原理图重点阐述了各参数指标的实现与测试方法。通过改变RC电路的电容充、放电路径和时间常数实现了占空比和频率的调节,通过多路开关投入不同数值的电容实现了频段的调节,通过电压取样和同相放大电路实现了输出电压幅值的调节并提高了电路的带负载能力,可作为频率和幅值可调的方波信号发生器。Multisim 10仿真分析及应用电路测试结果表明,电路性能指标达到了设计要求。 Abstract:  Based on Multisim 10, this paper designed a kind of rectangular-wave signal generator which could be controlled exactly composed of operational amplifier, the key point was how to implement and test the parameter indicators based on the circuit diagram. The duty and the frequency were adjusted by changing the time constant and the way of charging and discharging of the capacitor, the width of frequency was adjusted by using different capacitors provided with multiple switch, the amplitude of output voltage was adjusted by sampling voltage and using in-phase amplifier circuit,the ability of driving loads was raised, the circuit can be used as squarewave signal generator whose frequency and amplitude can be adjusted. The final simulation results of Multisim 10 and the tests of applicable circuit show that the performance indicators of the circuit meets the design requirements.

  • 浅析HDMI CTS v.1.3和兼容测试中的常见问题

    为了改进产品性能和兼容性,最新的HDMI compliance test specification (HDMI CTS) V.1.3增加了新的测试内容和定下了更严格的标准。大多数现在递交给HDMI授权测试中心(ATC) 的带有HDMI功能的电器都将按照HDMI CTS V.1.3 来测试。Analog Devices (ADI) 分别在美国的绿堡(Greensboro,NC), 东京, 台湾和北京设立了四家预测试中心为客户提供HDMI CT 测试以缩短客户产品上市的时间。在本文中我们将讨论HDMI CTS V.1.3新增加的一些重要内容。同时我们也将着重总结一些典型测试项目失败的原因和可能的修改方案。

  • This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in seve

    This algorithm was developed by Professor Ronald L. Rivest of MIT and can be found presented in several languages. What I provide to you here is a C++ derivative of the original C implementation of Professor Rivets. The library code itself is platform-independant and has been tested in Redhat Linux. I ve included the sample code and makefile that I used for the Linux test. The demo, however, was written with Visual C++ 6 on a Windows 2000 platform.

  • 1. 本移植也是从网上Download的

    1. 本移植也是从网上Download的,稍微做了一下整理. 移植除了OS_CPU.h,OS_CPU_A.s,OS_CPU_C.C 三个函数外 对中断专门用了一个函数OS_int_A.s 按其中的规则 写中断函数即可 2。应用实例为\ArmUCOS\App\test1\test.mcp,在周立功2104的扳子上 的ram中就可直接运行(code+data<16K), 注意使用了.a库文件 (我习惯这么用) 3. 将所有的文件放到D:\ArmUCOS\下,这样上面的文件能直接编译 3。若有疑问电zh_lyp@163.com
