The aim of this paper is the comparative estimation of the measurement uncertainty associated to the results of complex measurements, such as the evaluation of the wavelet transform of signals affected by transient disturbances. The uncertainty estimation is performed by means of two different methods: the approach suggested by the IEC-ISO “Guide to the Expression of Uncertainty in Measurement" and the one, recently proposed in the literature, based on the use of Random-Fuzzy variables. The comparison is performed starting from actual signals generated and acquired by means of a suitable test system.

Abstract

The aim of this paper is the comparative estimation of the measurement uncertainty associated to the results of complex measurements, such as the evaluation of the wavelet transform of signals affected by transient disturbances. The uncertainty estimation is performed by means of two different methods: the approach suggested by the IEC-ISO “Guide to the Expression of Uncertainty in Measurement" and the one, recently proposed in the literature, based on the use of Random-Fuzzy variables. The comparison is performed starting from actual signals generated and acquired by means of a suitable test system.
