4 p. : il.Two sampling algorithms that use a high-resolution voltmeter for accurately measuring the amplitudes and phase angles of the harmonics of a low-frequency, low-distortion, voltage waveform are presented. The technique is an extension to the frequency domain of a previously described approach. In the new approach, the harmonic parameters are evaluated by a least-squares, three-parameter, sine-fit algorithm. A faster algorithm that uses discrete Fourier transforms is also presented. The latter algorithm can estimate the parameters of harmonics of a 100-Hz low distortion waveform in less than 4 seconds. The relative standard uncertainty associated with the RMS estimate depends on the waveform stability, harmonic content, and noise var...
