Stochastic resonance in a discrete time nonlinear SETAR (1,2,0,0) model

Abstract

We present in this paper the stochastic resonance phenomenon in a discrete time context. Indeed, stochastic resonance has been commonly investigated in continuous-time. Analytical results given by a simple bistable nonlinear SETAR (1,2,0,0) are studied. Then, the ability of such a system to be used in signal processing is discussed.
