Abstract :
In this paper, a novel method for the estimation of the parameters of the spectral components of a signal, also in case of harmonic interference, is characterized and compared to other methods proposed in literature. The comparison criteria include the evaluation of the residual errors and of the uncertainties on the estimated parameters, for different multi-component signals.
