Research and Realization of High-accuracy Frequency Measurement
Jun Wu · Journal of Sichuan Normal University · 2008
The measurement's errors and their reasons in the direct frequence measurement and equal precision frequence measurement are analyzed in this paper.According to the regular phase change characteristic between the periodic signals,a concrete scheme realizing high-accuracy frequency measures has been brought forward.The periodic signals synchronous detection,the high-accuracy frequency measurement principle as well as the,measurement error are emphatically discussed.The main simulation profile has been imitated by the soft of MAX+plus II,and some discussions are made for the error.
