Stochastic resonance in an asymmetric bistable system
TLDR
In this paper, a simple bistable stochastic system with an overdamped Kramers oscillator featuring white noise and a periodic rectangular signal with a constant component was studied theoretically and using an analog model.Abstract:
The phenomenon of stochastic resonance in a simple bistable stochastic system, representing an overdamped Kramers oscillator featuring white noise and a periodic rectangular signal with a constant component, has been studied theoretically and using an analog model. An increase in the constant component, determining a static asymmetry of the potential, leads to a decrease in the signal to noise ratio as compared to the symmetric case.read more

Stochastic resonance: noise-enhanced order
TL;DR: Stochastic resonance (SR) as mentioned in this paper provides a glaring example of a noise-induced transition in a nonlinear system driven by an information signal and noise simultaneously, and some characteristics of the information signal (amplification factor, signal-to-noise ratio, the degrees of coherence and of order) at the output of the system are significantly improved at a certain optimal noise level.
