heal.abstract	The Hilbert transform together with Gabor's analytic signal provides a standard linear integral approach to estimate the amplitude envelope and instantaneous frequency of signals with a combined amplitude modulation (AM) and frequency modulation (FM) structure. A recent alternative approach uses a nonlinear differential 'energy' operator to track the energy required to generate an AM-FM signal and separate it into amplitude	en
