Abstract
The wavelet entropy (WE), a new quantity is introduced to describe the time-frequency character of an atomic clock. It can be obtained through synthesizing wavelet coefficients based on energy partition. We connected the Allan variance with the wavelet entropy, and used the WE to character the stability of a clock. The performance of the approach was examined by real data and the results demonstrated its validity in analyzing the characterization of clock behavior
