A New Method of Time Difference Measurement-The Time Difference Method by Dual "Phase Coincidence Points" Detection

Wei Zhou

Abstract:	In the high accurate measurement of periodic signals the greatest common factor frequency and its characteristics have special functions. This paper describes a new method of time difference measurement-the time difference method by dual "phase coincidence points" detection. This method utilizes the characteristics of the greatest common factor frequency to measure time or phase difference between periodic signals. It eon suit a very wide frequency range. Measurement precision and potential accuracy of several picoseconds have been demonstrated with this new method. The instrument based on this method is very simple, and the demand for the common oscillator is low. This method and instrument can be used widely.
