Analysis and Application of Atomic Clock Signal Based on EMD

摘要：

　　It is well known that a signal of atomic clock is effected by various noises.In order to obtain the high precision time scale, it is important and necessary to filter or weaken the noises from the atomic clocks signal.The smooth processing of the atomic clock signal may be realized by Hilbert-Huang transform.With empirical mode decomposition method, a clock s signal is decomposed into single component of intrinsic mode function.The main performance characteristics of an atomic clock are able to gotten by analyzing different components.
