ADC based measurements: A common basis for the uncertainty estimation
2010
In the last years, many Authors have dealt with the uncertainty evaluation of the measurement performed by using an analog-to-digital converter, proposing different approaches to analyze the uncertainty propagation. However, in these studies, in order to identify the uncertainty sources, different sets of parameters are used, and, often, it is not considered that the various uncertainty sources have different modalities of propagation. Obviously, this implies that the various proposed approaches are not directly comparable. One of the main reasons which has caused this situation is the coexistent of various Standards concerning the characterization of the analog-to-digital converters. There…
Montekarlo metodes pielietojums mērījumu nenoteiktības novērtēšanā
2022
Mērījumu nenoteiktība pastāv visiem mērījumiem. Darbā tiek aprakstītas mērījumu nenoteiktības novērtēšanas metodes. Tiek apskatīta metode, kas tiek aprakstīta GUM (Guide to the Expression of Uncertainty in Measurement) standartos un metode, kas balstīta uz Montekarlo simulācijām. Abas metodes tiek salīdzinātas gan ar kvantitatīvām, gan kvalitatīvām metodēm, izmantojot praktiskus piemērus.
