Stochastic Multiresonance

TL;DR

This paper introduces stochastic multiresonance, a phenomenon where the signal-to-noise ratio peaks at multiple noise levels, allowing for enhanced periodic signals at various noise intensities.

Contribution

It presents a new class of systems exhibiting multiple maxima in signal-to-noise ratio, expanding the understanding of stochastic resonance phenomena.

Findings

Signal-to-noise ratio shows multiple maxima with varying noise levels

Periodic signals can be enhanced at multiple noise levels

Extends stochastic resonance to multiresonance scenarios

Abstract

We present a class of systems for which the signal-to-noise ratio as a function of the noise level may display a multiplicity of maxima. This phenomenon, referred to as stochastic multiresonance, indicates the possibility that periodic signals may be enhanced at multiple values of the noise level, instead of at a single value which has occurred in systems considered up to now in the framework of stochastic resonance.
