Effects of additive noise on vibrational resonance in a bistable system
Effects of additive noise on vibrational resonance in a bistable system
We study the overdamped motion of a particle in a bistable potential subject to the action of a bichromatic force and additive noise, within the context of the vibrational resonance phenomenon. Under appropriate conditions, we obtain analytical expressions for the relevant observables which quantifies this phenomenon. The theoretical results are …
