Measurement of the Sinewave RMS Value in Noncoherent Sampling Case
Résumé
In this paper, a method to estimate the rms value of a noncoherent sampled sinewave by means of the formula used in an AC analog electronic voltmeter is presented. Adding some modifications on the algorithm, the accuracy obtained in this case was improved. This method is well suited for real-time applications in which the measurement of the sinewave rms value with relative high accuracy is sufficiently. The performances of the method proposed are proved by means of computer simulation as well as experimental results.
