Divergent signal-to-noise ratio and stochastic resonance in monostable systems Vilar, J. M. G. (José M. G.), 1972- Rubí Capaceti, José Miguel Termodinàmica Mecànica estadística Thermodynamics Statistical mechanics 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. 2010-06-25T08:36:37Z 2010-06-25T08:36:37Z 1996 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció digital del document proporcionada per PROLA i http://dx.doi.org/10.1103/PhysRevLett.77.2863 Physical Review Letters, 1996, vol. 77, núm. 14, p. 2863-2866 http://dx.doi.org/10.1103/PhysRevLett.77.2863 (c) American Physical Society, 1996 info:eu-repo/semantics/openAccess American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
