Stochastic resonance in bistable systems: The effect of simultaneous additive and multiplicative correlated noises

TL;DR

This paper investigates how correlated additive and multiplicative noises influence stochastic resonance in bistable systems, revealing that modulating the correlation parameter can make the system's response insensitive to additive noise intensity.

Contribution

It introduces the analysis of correlated noises with a modulated correlation parameter and its impact on stochastic resonance in bistable systems.

Findings

Response becomes independent of additive noise when correlation is modulated.

Correlation modulation affects the stochastic resonance response.

System's output signal-to-noise ratio is influenced by noise correlation.

Abstract

We analyze the effect of the simultaneous presence of correlated additive and multiplicative noises on the stochastic resonance response of a modulated bistable system. We find that when the correlation parameter is also modulated, the system's response, measured through the output signal-to-noise ratio, becomes largely independent of the additive noise intensity.
