Abstract :
This work deals with the problem of harmonic and interharmonic identification in presence of additive white noise. Towards this end, it is proposed an improvement on the well known Prony´s method. It is tested on both synthetical and experimental signals and the results are compared with the ones obtained by the classical Prony´s Method and by the fast Fourier transform (FFT)
