For this purpose, we have considered two types of modulations, namely, variations of the resistance and oscillations of the threshold. In both cases, stochastic resonance is present, irrespective of whether the system is monostable or bistable.8 p.application/pdfeng(c) American Physical Society, 1999Física mèdicaFísica estadísticaTermodinàmicaSistemes no linealsMedical physicsStatistical physicsThermodynamicsNonlinear systemsinfo:eu-repo/semantics/article514135info:eu-repo/semantics/openAccess
