| Zusammenfassung | We consider the task of uncertainty evaluation in the context of dynamic measurements. We assume that the relation between the time-dependent value of the measurand and the available output signal of an employed sensor is governed by a linear time-invariant system. Estimation of the measurand is done by applying a digital filter to the sensor’s output signal. We propose a method for uncertainty evaluation which is in line with the Guide to the Expression of Uncertainty in Measurement (GUM). The method accounts for dynamic errors due to non-perfect compensation of the dynamic behavior of the sensor, and it allows for real-time calculation when a causal digital filter is employed. The proposed uncertainty calculation method can be used to design an uncertainty optimum filter. We illustrate the procedures in terms of a simple example. |
