We reconsider stochastic resonance (SR) for an overdamped bistable dynamics driven by a harmonic force and Gaussian noise from the viewpoint of the gain behavior, i.e., the signal-to-noise ratio (SNR) at the output divided by that at the input. The primary issue addressed in this work is whether a gain exceeding unity can occur for this archetypal SR model, for subthreshold signals that are beyond the regime of validity of linear response theory: in contrast to nondynamical threshold systems…

Subthreshold stochastic resonance: rectangular signals can cause anomalous large gains.
TLDR
With subthreshold amplitudes and for an appropriate duration of the pulses of the driving force, the phenomenon of stochastic resonance is accompanied by SR gains exceeding unity, which sheds light on the interplay between nonlinearity and the nonlinear response.
SIGNAL-TO-NOISE RATIO GAIN IN NON-DYNAMICAL AND DYNAMICAL BISTABLE STOCHASTIC RESONATORS
It has recently been reported that in some systems showing stochastic resonance, the signal-to-noise ratio (SNR) at the output can significantly exceed that at the input; in other words, SNR gain is…
Gain in stochastic resonance: precise numerics versus linear response theory beyond the two-mode approximation.
TLDR
It is found that the gain can exceed unity in the strongly nonlinear regime which is characterized by weak noise and very slow multifrequency subthreshold input signals with a small duty cycle.
Weak-Periodic Stochastic Resonance in a Parallel Array of Static Nonlinearities
TLDR
In an array of suboptimal but easily implemented threshold nonlinearities, the feasibility of situations where stochastic resonance occurs is shown, and also the possibility of the SNR gain exceeding unity for a wide range of input noise distributions.
Stochastic resonance in finite arrays of bistable elements with local coupling
AbstractIn this article, we investigate the stochastic resonance (SR) effect in a finite array of noisy bistable systems with nearest-neighbor coupling driven by a weak time-periodic driving force.…

Signal-to-noise ratio gain in stochastic resonators driven by colored noises
We studied two non-dynamical stochastic resonators, the level-crossing detector (LCD) and the Schmitt trigger, driven by a periodic pulse train plus 1/fκ-type coloured noises, and we have examined…
Stochastic resonance: theory and numerics.
TLDR
This work addresses the phenomenon of stochastic resonance in a noisy bistable system driven by a time-dependent periodic force and in its two-state approximation and introduces analytical and numerical tools to analyze the power spectral amplification and the signal-to-noise ratio in a nonlinear regime.
Noise improvement of SNR gain in parallel array of bistable dynamic systems by array stochastic resonance
We report the regions where a signal-to-noise ratio (SNR) gain exceeding unity exists in a parallel uncoupled array of identical bistable systems, for both subthreshold and suprathreshold sinusoids…
