提出一种在遥测系统中PCM码同步时钟快速恢复的新方法,与过去使用的模拟/数字锁相环法进行了比较,并以此设计出一种快速、宽带、高精度的PCM码时钟的再生电路。同时给出了该电路的性能分析及实验结果。
A new method for fast recovery of PCM code synchronization clock in telemetering system is proposed, which is compared with the analog / digital phase locked loop method used in the past and designs a fast, wideband and high precision PCM code clock Regeneration circuit. At the same time, the circuit performance analysis and experimental results are given.
