Suprathreshold stochastic resonance: suppression of noise by strong periodic signals
Abstract
Description
We consider an overdamped Brownian motion in "quartic" potential subjected to periodic driving. This system for the case of a weak periodic driving has been intensively studied during past decade within the context of stochastic resonance. We had demonstrated, that for the case of predominantly suprathreshold driving the noise in the output signal is strongly suppressed at certain frequency range: the signal-to-noise ratio demonstrates resonant behavior as function of frequency.
