heal.abstract	The statistical properties of the nonlinear energy operator Ψ( s)=(ds/dt)2-sd2 /dt2 and a related energy separation algorithm (ESA) are developed. The ESA uses Ψ to demodulate noisy AM-FM signals. The performance of Ψ and the ESA when applied to bandpass noisy AM-FM signals is examined. The predicted performance is found to be greatly improved if the local signal frequencies occur	en
