电子常识计算延时线的最高工作频率摘要:延迟线在应用中要求一个(纳秒),或者增量时间更正为系统正常工作所需的几纳秒信号延迟。This application note discusses the maximum frequency thatthe input signal could have,and the maximum delay that can be obtained.本应用指南讨论了最高频率的输入信号可以,最大的延迟可以得到。A similar version of this article was published on February24,2009on theIndustrial Control DesignLinewebsite.这个类似文章发表在2009年2月24日在工业控制DesignLine网站。Calculating Maximum Input Frequency计算最大输入频率When calculating the maximum input frequency,the critical parameter toconsider is the minimum pulse width of the input signal.当计算的最大输入频率,最重要的参数要考虑的是输入信号的最小脉冲宽度。For periodic signals with a50%duty cycle,the minimum pulse width wouldbe half the period of the signal.对于具有
