  • Abstract
    This paper describes the signal processing used in the development of a power quality standard for calibrating commercial harmonic analyzers. High precision digitizers of 27 bits are used to get the requested accuracy, but they have low sampling rates. This drawback limits the maximum harmonic content that the analyzer can measure. This paper shows an application to avoid the Nyquist frequency limit allowing the computation of harmonic frequency up to twice that limit.
