The Technology Of Phase Processing Based On Equivalent Phase Comparison Frequency

With the extensive application of the technology of time and frequency, phase processing technology applied in must be father advanced. It is in-depth study of the concepts of Equivalent Phase Comparison Frequency and Quantized Phase Variation Resolution, put forward to the concepts Group phase differences and Groups phase quantum,and analyze in detail its characteristics. The concepts of Equivalent Phase Comparison Frequency and so on are used to the phase processing domain for instance: the measurement of frequency stability and frequency, the improvement of Phase-Locked Loop (PLL) and active hydrogenous atom frequency standard, which can simplify system,reduce noise and raise resolution.It is introduced others applications of Equivalent Phase Comparison Frequency in the last of this paper such as: be applied to explain essentially periodic phenomena in nature and raise to a very great extent the resolution of time and frequency measurement in the study of Time comb.
