Time Interval Averaging: Theroy,Problems,and Solutions
Wang Xue (The Colledge of Information Science and Tecnology Jinling Institute of Tecnology,JiangSu,Nanjing,210001)
This article introduces the principle of the time interval averaging,and analyzes that time interval measurement can cause non-average and coherence of bandwidth problem. It is also explains time base random phase modulation. Two type of errors in time interval averaging have been discussed: non averaging bias error,and time base short-term uncertainty error. As mentioned above,in practical application,it plays an important role in guiding to select technology of this kind of relevant instruments.
