Abstract

A novel approach of signal extraction of a harmonic component from a chaotic signal gen erated by a Duffing oscillator is proposed. Based on empirical mode decomposition(EMD) and con cept that any signals were composed of a series of the simple intrinsic modes, the harmonic compo nents were extracted from the chaotic signals. Simulation results show the approach is satisfactory.
