摘要
根据SDH中TU指针调整的特点,提出一种自适应比特泄漏器软件和硬件协同工作的设计方法,用来扩散指针调整引起的抖动。阐述了随机信号的构成、软件流程设计、硬件电路设计以及软硬件协同工作的方法,给出了SDH结合抖动中4种测试码的实验结果。
According to the characteristic of tributary unil（TU） point justification in synchronous digital hierarchy （SDH）, this paper provides a method of software and hardware for designing adaptive bit-leaking. The content is a solution of making random signal, designing the software flow, and circuit design. Then it gives the result of four tests for combined jitter measurement in SDH.
