延迟锁相环的研究

本文简述了延迟锁相环的工作原理,介绍了环路的主要环节,如a—b变换,环路泸波器、VCo等,对特性曲线进行了定性和定量的分析,并将网络的主要技术指标:同步带、捕捉带、剩余相位差等,作了较准确的测量,从理论上对同步带和捕捉带进行了计算。

STUDY OF LOOP OF DELAY LOCK PHASE

The work principle of loop of delay lock phase is described,and some main links in the loop ,such as the change from a to b, filter of loop,and VCO axe introduced. So the qualitative and quantitative analysis about response is given. The main techno-logy targets , such as synchronism band, catch band, remainder phase difference, are measured exactly. The synchronism band and catch band are caculated in theory. This technololgy achieves good rresults in theory and practice.
