This paper presents the study of signal smoothing techniques, in order to select the best for use in a specific type of problem: determination of oxidative stability, by the computational calculation of the induction period. The oxidative stability is one of the major quality parameters of biofuels. According to some established hypotheses and metrics, the results of the study are presented, culminating in the identification of best available techniques related to each metric. This work also contains a case study presenting real use of the smoothing techniques in a signal collected by Ozomat (equipment for determining the oxidative stability).
