Abstract
Evolutionary spectral theory defines a decomposition of signal energy jointly over time and frequency by assuming that processes are composed of sinusoidal components with time-dependent amplitudes. We expand this theory by allowing time variations in the frequency of the sinusoidal components. Examples are presented illustrating the advantages of this generalization
