摘要
TDR作为通信电缆线路长度测量和故障点距离定位的方法得到了广泛的应用,该文针对现有方法测量距离短、故障定位不准的缺陷,提出了几种提升TDR性能的高级算法,包括数字滤波、信号流图等.
TDR measurement is used extensively as a method of line length measurement and fault detection for telecom cable.This paper describes some advanced algorithms to promote the TDR performance,including digital filter,signal flow graph and mason gain expression.
