Abstract :
The problem of uncertainty analysis in digital signal processing algorithms is discussed, proposing a method based on a `white box´ approach. A theoretical uncertainty estimation is carried out first; its results are then confirmed by both simulation and experimental tests. The characteristics of the method are highlighted by means of a practical application to some common algorithms for measurements on periodic signals
