Divergent Signal-to-Noise Ratio and Stochastic Resonance in Monostable Systems
arXiv:cond-mat/9609077 · doi:10.1103/PhysRevLett.77.2863
Abstract
We present a class of systems for which the signal-to-noise ratio always increases when increasing the noise and diverges at infinite noise level. This new phenomenon is a direct consequence of the existence of a scaling law for the signal-to-noise ratio and implies the appearance of stochastic resonance in some monostable systems. We outline applications of our results to a wide variety of systems pertaining to different scientific areas. Two particular examples are discussed in detail.
