- Abstract:
- The paper deals with the measurement uncertainty evaluation of the PC-based measurement instruments, by using the effective number of bits, that is a well know parameter, usually employed to characterise the overall behaviour of an A/D converter. In order to verify if this parameter can be also used to assess the measurement uncertainty, we use an ad-hoc developed software tool. The results show that using the effective number of bits can lead to an underestimate of the uncertainties.
