  • LTC1099基于PC的数据采集板实现

    A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Tur ...

  • 高速电路传输线效应分析与处理

    随着系统设计复杂性和集成度的大规模提高,电子系统设计师们正在从事100MHZ以上的电路设计,总线的工作频率也已经达到或者超过50MHZ,有一大部分甚至超过100MHZ。目前约80% 的设计的时钟频率超过50MHz,将近50% 以上的设计主频超过120MHz,有20%甚至超过500M。当系统工作在50MHz时,将产生传输线效应和信号的完整性问题;而 ...

  • 利用高压看门狗定时器加强汽车安全系统

      Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" ...
