Resonance behaviour for a bistable system driven by random-phase square-wave signal-modulated noise and multiplicative noise
The stochastic resonance (SR) phenomenon for a bistable system subject to signal-modulated noise and to multiplicative and additive noise is investigated. The signal is modelled as a random-phase asymmetric sq...
