Abstract :
An algorithm that uses an integrating voltmeter for accurately estimating the harmonic magnitudes of periodic arbitrary signals is presented. The uncertainties associated with the magnitude estimates relative to the fundamental depend on signal stability, harmonic content, noise variance and are less than 1 times 10-5 for signals with up to 64 harmonics
