The influence of the memory effect on stochastic resonance

Stochastic resonance (SR) is a phenomenon where a signal, typically too weak to be detected by a sensor, can be amplified by introducing white noise containing a broad spectrum of frequencies. Frequencies within the white noise that align with those of the original signal resonate, amplifying the original signal while leaving the rest of the white noise unaffected. This process enhances the signal-to-noise ratio, thereby making the original signal more discernible. Stochastic resonance finds application in nonlinear, bistable systems. Our report delves into this method, which we employ for energy extraction. The model discussed in the presentation, specifically the double potential well, illustrates how noise impacts the system, demonstrated through numerical experiments and modeling.
