Paper Abstract

We report on stochastic resonance in an array of four unidirectionally coupled Schmitt triggers driven by global noise and a spatiotemporal modulation. By introducing phase shifts in the drives of these bistable electronic triggers we were able to control the amplification of the periodic input signal, which is a characteristic of stochastic resonance. For phase shifts allowing for periodic boundary conditions, we found array-enhanced stochastic resonance. Moreover, evidence for spatiotemporal stochastic multiresonance was obtained, where the array exhibits more than one maximum of amplification. We attribute these phenomena to a competition between the external drive and the coupling of an array element with its neighbor.
