Energy Demodulation of Two-component AM-FM Signal Mixtures
is the Teager-Kaiser energy operator [4], [5] and dots denote time derivatives. The ESA is efficient and has very low computational complexity and excellent time resolution. However, if x ( t ) is a multicomponent AM-FM signal, then bandpass filtering is needed to isolate each component before applying the ESA. The bandpass filtering causes problems when the components have overlapping spectra. In this paper, we present the energy demodulation of mixtures (EDM) algorithm for the demodulation of two-component AM-FM signals of the form
