The concept of controlling stochastic resonance has been recently introduced ͓L. Gammaitoni et al., Phys. Rev. Lett. 82, 4574 ͑1999͔͒ to enhance or suppress the spectral response to threshold-crossing events triggered by a time-periodic signal in background noise. Here, we develop a general theoretical framework, based on a rate equation approach. This generic two-state theory captures the essential features observed in our experiments and numerical simulations. PACS number͑s͒: 05.40.Ϫa,
