    Abstract

    Stochastic resonance in two coupled threshold elements with input periodic signals shifted in phase is studied. For fixed phase shift and coupling strength the signal-to-noise ratio at the output of each element can be maximized by introducing proper time delays in the coupling terms which cancel the effect of the phase shift. This shows that in systems of coupled elements driven by spatiotemporal periodic signals stochastic resonance can be controlled by delayed coupling.
