摘要
本文介绍了脉冲吞除原理,分析了基于该原理的小数频率合成方法及其在SN368地震数据采集系统中的应用情况,对小数频率合成器中的相位补偿问题进行探讨,分析了一种可用微处理器和D/A转换器实现的相位补偿方案.
This paper introduces the principles for pulse swallowing,the decimal frequency synthesismethod based on that and analyses its application in the 5386 Telmetry Seismic Data Acquization System.Thephase compensation for the decimel frequency synthesizer is discussed.A method of the phase compensation isanalysed which may be implemented by a system made of a microprocessor and a D/A converter'
