Signals Featuring Harmonics With Random Frequencies โ Spectral, Distributional and Ergodic Properties
An interesting class of non-Gaussian stationary processes is obtained when in the harmonics of a signal with random amplitudes and phases, one allows also for frequencies to vary randomly. In the resulting models, the statistical distribution of frequencies determines the process spectrum while the distribution of amplitudes governs the process โฆ
