摘要
从 PCM数据序列中直接提取码同步是目前遥测系统中最常用的一种同步方法。介绍一种在实验教学遥测系统中采用的简易的全数字锁相环码同步器 ,对这种码同步器的设计思想。
Picking up the bit-synchronization signal directly from PCM sequence is one of the most common method in telemetry system at present.A facile digital loop bit synchronizer used in telemetry system demonstration is described in this paper.The design idea,hardware compsition and operation principle of this bit synchronizer are introduced.
