【Abstract】 A new method for harmonic analysis of periodic signals is introduced, the aim is to realize the harmonic measurement precise in non-synchronization sampling. By using the signal period precision measurement techniques, catching the integer number signal periods, cutting out the effect of the average value of the periodic signals, one can get higher measurement accuracy of harmonic analysis, the precision harmonic measurement has been realized. The error analysis is also presented. Through a simulation experiment, the rightness and feasibility is proved. The method in this paper can be used to harmonic measurement in non-synchronization sampling.更多还原
