From a metrological point of view, a measurement process rarely consists of a direct measurement but, rather, of digital signal processing (DSP) performed by one or more instruments. The measurement algorithm makes the numerical results available as functions of acquired samples from input signals. Moreover, when repeated direct measurements are performed,(More)
The demands of statistical investigations in measurements inspired the remarkable development of probabilistic methods [1]. However, the probability theory didn’t prove to be fully adequate for all types of uncertainty. Probability theory is excellent if the ambiguity is to be modelled, but its attempts to describe vagueness is quite inconsistent with(More)
In the present work the authors present the realization of a Virtual Instrument implementing a selfcalibrating THD Meter. The instrument is able to draw an electrical signal provided from a phase of the electrical distribution network, and to evaluate its Total Harmonic Distortion (THD). Actually the instrument calibration process is developed in two times:(More)
