Resumen:
We study an extended system that without noise shows a spatiallyhomogeneous state, but when submitted to an adequatemultiplicative noise, some extit{noise-induced patterns} arise.The stochastic resonance between these structures is investigatedtheoretically in terms of a two-state approximation. The knowledgeof the exact nonequilibrium potential allows us to obtain theoutput signal-to-noise ratio. Its maximum is predicted in thesymmetric case for which both stable attractors have the samenonequilibrium potential value.
