Both coherence resonance (CR) and stochastic resonance (SR) in a delayed bistable system driven by additive and multiplicative white noises and a weak harmonic excitation are studied by using the theory of two-state model. For the weak noise intensity and delayed feedback, the analytic...

In this article, some prominent phenomena in a two-dimensional square array of coupled nonlinear oscillators driven by a periodic signal plus white noise are presented: (i) For a subthreshold periodic signal (A⩽1-b), besides conventional stochastic resonance (SR) as a best cooperative result...
