一种减小SDH指针调整抖动的方法

A New Method of Reducing the Pointer Adjustment Jitter in SDH

ＳＤＨ指针调整抖动是ＳＤＨ网的主要传输损伤之一，如何抑制它已成为研究ＳＤＨ的关键技术之一。文中提出一种新的抑制指针调整抖动的方法——数字滤波法，并分析了它的原理和实现方法。

The jitter induced by pointer adjustment is one of the main impairments in SDH netwerk,and how to reduce it is one of the key technical problems in SDH research.This paper proposes a new method of reducing the pointer adjustment jitter,gives the theoretical analysis,implementation and simulation results.
