Stochastic Resonance in a Discrete Time nonlinear Syste with Cyclostationary Inputs
Résumé
In this paper we investigate the stochastic resonance phenomenon in a discrete time system, for cyclostationnary inputs. The results for the recursive ``sign'' filter, for two cyclostationnary inputs - sine corrupted by an additive, and a multiplicative noise - are presented. We show in both cases, for a gaussian and uniform noise, that this system generate a stochastic resonance like phenomenon.
