Abstract

We consider a noise-free bistable system with a low frequency signal and a secondary harmonic excitation that causes the systemto experience chaotic motion with a broadband portion of the output spectrum. The signal-to-noise ratio (SNR) is defined on thebasis of this broadband spectrum. We present the theorical background for approximate calculation of the hopping rate, the outputspectra and SNR of the system. It is shown that, under a proper choice of the secondary excitation, the SNR can be enhanced. Thisphenomenon is referred to as chaotic resonance. We show similarities between results obtained for chaotic resonance on the onehand and classical stochastic resonance induced by random perturbations on the other. As an example, chaotic resonance in theHolmes-Brunsden oscillator is studied.
