Auto-evaluation of the uncertainty in virtual instruments

2002 
A numerical approach based on a Monte Carlo probabilistic method is used as an advantageous alternative to the traditional analytical methods for the evaluation of the uncertainty in measurements achieved by digitally processing sampled input data. The correctness of the approach is shown in the case of both single-channel and multi-channel systems. Some practical concerns about the reliability of the proposed methodology are discussed and suitably designed virtual instruments are presented that are able to present the measurement result along with its uncertainty.
