Stochastic resonance (SR) is shown in a two-parameter system, a model of electrodissolution of Fe in H₂SO₄. Modulation of two different parameters by a periodic signal in one parameter and noise in the other parameter is found to give rise to SR. The result indicates that the noise can enlarge a weak periodic signal and lead the system to order. The scenario and novel aspects of SR in this system are discussed.
