We enhance the response of a “stochastic resonator” by coupling it into a chain of identical resonators. Specifically, we show via numerical simulation that local linear coupling of overdamped nonlinear oscillators significantly enhances the signal-to-noise ratio of the response of a single oscillator to a time-periodic signal and noise. We relate this array enhanced stochastic resonance to the global spatiotemporal dynamics of the array and show how noise, coupling, and bistable potential… Expand

Stochastic resonance in coupled nonlinear dynamic elements.
TLDR
The response of a linear chain of diffusively coupled diode resonators under the influence of thermal noise is investigated and analytical results for the synchronization and signal processing properties of a Phi(4) field theory are presented. Expand
Stochastic Resonance in a Coupled Array Without Periodic Driving
We manifest a stochastic resonance in a two-dimensional square array of coupled oscillators subjected only to white noise and constant driving forces. The result shows that the coherent output of… Expand
Noise-induced synchronized switching in coupled bistable systems
TLDR
It is shown that noise and coupling cooperate to organize spatio temporal order across the array, corresponding to an increase in the output SNR of the reference element of a single element when it is coupled into an array of like elements. Expand
ENHANCEMENT OF STOCHASTIC RESONANCE IN SPATIALLY EXTENDED SYSTEMS BY MEANS OF DELAYED COUPLING
Stochastic resonance in a chain of coupled threshold elements driven by a spatiotemporal periodic signal and noise is studied. It is shown that stochastic resonance can be enhanced for a fixed… Expand
Multi Signal Amplification by Stochastic Resonance
We study numerically the stochastic resonance in a bistable system driven simultaneously by gaussian noise and a composite signal consisting of at least two basic frequencies. We show that by tuning… Expand
Spatiotemporal stochastic resonance in an array of Schmitt triggers
We report on stochastic resonance in an array of four unidirectionally coupled Schmitt triggers driven by global noise and a spatiotemporal modulation. By introducing phase shifts in the drives of… Expand
SIGNAL TRANSFER AND STOCHASTIC RESONANCE IN COUPLED NONLINEAR SYSTEMS
A model of coupled nonlinear oscillators is discussed, wherein Langevin-type bistable systems are combined with self-sustained oscillators. An external harmonic signal is coupled in a subthreshold… Expand
System size stochastic resonance in driven finite arrays of coupled bistable elements
AbstractThe global response to weak time periodic forces of an array of noisy, coupled nonlinear systems might show a nonmonotonic dependence on the number of units in the array. This effect has been… Expand

TLDR
In systems of coupled elements driven by spatiotemporal periodic signals stochastic resonance can be controlled by delayed coupling by introducing proper time delays in the coupling terms which cancel the effect of the phase shift. Expand
Array-enhanced stochastic resonance in finite systems
Abstract A finite system of three coupled stochastic resonators is investigated with respect to the coupling constant. The consideration allows the analytical calculation of the spectral power… Expand
