摘要

针对模拟传输方式脉冲传输抖动较高、接收门限较高的情况，提出了数字化低抖动脉冲传输方法。介绍了脉冲信号的数字化传输原理，对传输过程中的脉冲抖动成因进行了分析与优化。给出了具体的设计方案，对测试数据进行了比较和分析。结果表明，采用数字化传输方法，脉冲传输抖动低，接收门限低。%With respect to the high transmission jitter and high receiving threshold level of analog pulse transmission,a digitization method for lower jitter pulse transmission is proposed.The digitized pulse transmission principle is introduced.The factors leading to digi⁃tized transmission jitter are analyzed and optimized.Detailed design schemes are given.By analyzing test data,it is indicated that the dig⁃itized pulse transmission method can realize lower transmission jitter and lower receiving threshold level.
