Abstract

The power spectral density Q(w) for an electronic circuit model of the double-well Duffing oscillator, driven by Gaussian white noise, has been measured in the limit of very low damping. Three distinct maxima and a plateau region are found in Q(w), in excellent qualitative agreement with a recent theoretical prediction by Dykman and co-workers.
