Fractional moment spectra and related results

Abstract

The authors consider the following problems: (a) What is the p.d.f. with maximum entropy subject to cumulant constraints? (b) Given that a signal consists of two harmonics of unknown frequencies, how can they determine whether both the harmonics are phase-coupled to another unobservable harmonic whose frequency is unknown? (c) When is it inappropriate to use cumulants in transient analysis and related problems where the signal is deterministic?.<>
