UNCERTAINTY EVALUATION OF THE PROCESSING ALGORITHM OF A TIME-VARIABLE QUANTITIES IN MULTI-CHANNEL MEASUREMENT SYSTEMS
Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 3
Abstract
In this paper the application of the generalised law of uncertainty propagation in determining the standard uncertainty of measurement in a multi-channel sampling transducer has been proposed. It has been shown that for time-variable quantities one of the sources of processing uncertainty is the timing jitter between the successive samples and particular channels of the transducer. The influence of the uncertainty propagation related to the quantization and sampling of time variable signals by the processing algorithm has been analysed. The analysis results have been used for the uncertainty propagation evaluation in an impedance components measurement circuit.
