We discuss the dynamical behaviour of multi-threshold systems in the presence of noise and periodic inputs. Here, the stochastic resonance phenomenon displays some peculiarities such as a clear dependence on the noise statistics and the presence of a multi-peaked characteristic curve, which are not observed in simple bistable systems. This phenomenon is described without reference to any frequency matching condition as a special case of the well-known dithering effect.

Abstract
We discuss the dynamical behaviour of multi-threshold systems in the presence of noise and periodic inputs. Here, the stochastic resonance phenomenon displays some peculiarities such as a clear dependence on the noise statistics and the presence of a multi-peaked characteristic curve, which are not observed in simple bistable systems. This phenomenon is described without reference to any frequency matching condition as a special case of the well-known dithering effect.File in questo prodotto:
