Phys. Rev. Lett. 77, 2863–2866 (1996)Divergent Signal-to-Noise Ratio and Stochastic Resonance in Monostable SystemsReceived 7 June 1996; published in the issue dated 30 September 1996 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. © 1996 The American Physical Society URL:
