A Novel Harmonic Calculating Method Based on Multiple-Average Algorithm

On the base of fundamental principle of multiple-average harmonic Algorithm, a novel Harmonic calculating method is proposed, by which the amplitude and phase of every harmonics can be calculated accurately and conveniently. Computer simulation and physical experiment prove that the Algorithm has very high accuracy. Further, the influence of noise at samples to the result has been discussed by Monte Carlo method and given a qualitative result for practical engineering application.
