In this talk we will introduce a non-probabilistic theory for the harmonic analysis of power signals, which will highlight some key differences with respect to the similar and better investigated harmonic analyis of energy signals. For instance, we will prove that the bandwidth of the power spectrum of a signal does not always coincide with the bandwidth of the Fourier transform of the same signal. Among other topics we will cover: the sampling of power signals and the effects of frequency sampling on the spectra of these signals, the study of some algorithms for the numerical computation of power spectra, and an analyis of the errors introduced by such algorithms in the spectral estimates that they generate.
