Stochastic giant resonance

Physical Review E, 2007
The model of an electric circuit with dichotomous resistance is investigated. It is shown that the dichotomous resistance can induce a phenomenon of stochastic giant resonance for the signal-to-noise ratio (SNR) as a function of input signal frequency.

Stochastic Resonance in Bistable Systems

Physical Review Letters, 1989
The relaxation properties of a stochastic bistable system perturbed by a periodic low-frequency forcing term is investigated by means of analog simulation. The so-called stochastic resonance phenomenon is revealed under diverse experimental conditions. Its dependence on the parameters of both the periodic perturbation and the forced system is explained

Stochastic resonance: Theory and numerics

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2005
We address the phenomenon of stochastic resonance in a noisy bistable system driven by a time-dependent periodic force (not necessarily sinusoidal) and in its two-state approximation. Even for driving forces with subthreshold amplitudes, the behavior of the system response might require a nonlinear description.

A new definition of stochastic resonance

Il Nuovo Cimento D, 1995
Stochastic resonance in a bistable potential is characterized as a syncronization effect of the hopping mechanism induced by the external periodic bias. Most notably, syncronization is shown i) to attain a maximum with increasing the forcing frequency close to the relevant switching rate, thus revealing abona fide resonant process; ii) to occur even in

Comparison of stochastic adaptation and stochastic resonance

Physical Review E
Stochastic resonance is a phenomenon possessed by some nonlinear oscillators, in which a weak signal is boosted by noise. Both the monostable and bistable Duffing oscillators can exhibit this property. However, stochastic resonance has a strong frequency-dependence, as only a band of frequencies may be boosted by noise.

Noise-Induced Resonances: Stochastic Resonance, Resonant Activation, and Stochastic Ratchets

2018
Our world is replete with noises. In common sense a noise is a nuisance that blocks coherence; you feel annoyed with ambient sound noises when listening to music. In this chapter we will study a counter-intuitive phenomenon, called stochastic resonance (SR) , where a periodically modulated perturbation or signal too weak to be detected can be enhanced ...
