Stochastic resonance in a locally excited system of bistable oscillators
Stochastic resonance is studied in a one-dimensional array of overdamped bistable oscillators in the presence of a local subthreshold periodic perturbation. The system can be treated as an ensemble of pseudospins tending to align parallel which are driven dynamically by an external periodic magnetic field. The oscillators are subjected to a dynamic white noise as well as to a static topological...

Stochastic resonance is a counter-intuitive con system induces coherent amplification of i mechanism for the cyclic recurrence of ice ag in a wide variety of macroscopic physical syst magnetoelastic ribbons, and neurophysiolog crickets and crayfish. Although it is fundam coherent signal amplification, stochastic reson systems. Here we report the observation nanomechanical silicon oscillators, w...
متن کاملStochastic resonance in coupled underdamped bistable systems.
We study onset and control of stochastic resonance (SR) phenomenon in two driven bistable systems, mutually coupled and subjected to independent noises, taking into account the influence of both the inertia and the coupling. In the absence of coupling, we found two critical damping parameters: one for the onset of SR and another for which SR is optimum. We then show that in weakly coupled syste...
متن کاملResidual aperiodic stochastic resonance in a bistable dynamic system transmitting a suprathreshold binary signal.
Conventional stochastic resonance can be viewed as an amplitude effect, in which a small (subthreshold) input signal receives assistance from noise to trigger a stronger response from a nonlinear system. We demonstrate another mechanism of improvement by the noise, which is more of a temporal effect. An intrinsically slow system has difficulty to respond to a fast (suprathreshold) input, and th...
