Abstract

Abstract:

The rubidium atomic clock is most commonly used. The traditional circuit scheme usually adopts the comparison of the same frequency signals as a closing loop. Due to the existence of many frequency multipliers, the short stability of the rubidium clock is changing. Based on the principle of phase group synchronization and phase group continuation, the construction of the clock is improved by the frequency link in the generalized phase processing. The frequency link method in the generalized phase processing is spreading into the phase measurement between different frequency signals. Compared with the traditional method, the scheme simplifies the frequency transforming circuit and decreases the phase noise from them. With the simple construction the phase group synchronization improves the stability and reduces the phase noise.

Key words: atomic clock, frequency link, phase group synchronization
