| Abstract: | In order to have a better understanding of the characteristic of time - domain frequency stability of the atomic clock, the estimators of the various variances are first given in the paper. Then the analysis of the effect of the main error sources on the time - domain frequency stability is carried out, which include power law noises, frequency drift, dead time, periodic components and etc. And the corresponding modified method to the Allan variance is also given. |
