摘要
本文介绍一种周期信号谐波分析的新方法——准同步采样谐波分析法,能有效地减小同步偏差(采样周期与信号周期的偏差)对测量结果的影响,使基波与高次谐波均能获得相当高的测量准确度。据此原理制作的谐波分析仪已通过技术鉴定。
In this paper,a new method,namely quasisynchronous samplingharmonics analysis for spectrum analysis of periodic is signals proposed.Bythis method,the error due to the synchronous derivation(the noncoincidencebetween the sampling period and the signal period)can be reduced considerab-ly,and the measuring accuracies of the fundamental and especially higher-order harmonics can be much improved.
