Abstract
Evolutionary spectral theory defines a decomposition of signal energy jointly over time and frequency by assuming that processes are compose d of sinusoidal components with time-dependent amplitudes. me expand t his theory bg allowing time variations in the frequency of the sinusoi dal components. Examples are presented illustrating the advantages of this generalization.
