An Improved All-Wave Fourier Algorithm For Micro-Computer Alternating Current Sampling Calculations

摘要

This paper presents an improved all-wave Fourier algorithm for AC sampling systems. The new algorithm .which is improved from a normal all-wave Fourier algorithm,can obtain higher computation precision,even if the sampling period is imprecise. The improved all-wave Fourier also suits for fixed time sampling way.Under the fixed time sampling way,the new algorithm can reduce computation interval.So the improved all-wave Fourier algorithm has the advantages of all-wave and half-wave Fourier algorithm.
