Equivalent comparison and analysis between different nominal frequencies

doi:10.1088/1674-1056/23/11/110602

Abstract We analyze the phenomena of phase group synchronization between the different nominal frequency signals and propose a new theory of the equivalent comparison between them. The exact expression of the equivalent comparison is deduced. High resolution frequency measurement and phase comparison can be realized using this theory with the divider. For avoiding the frequency mixing, multiplication and synthesis, the system phase noise is improved and the higher resolution comparison and measurement are achieved between the different nominal frequencies by theory.

Keywords: phase difference group synchronization equivalent comparison frequency measurement
