The stochastic resonance (SR) in a second-order linear system driven by a trichotomous noise and an external periodic signal is investigated. By the use of the properties of the trichotomous noise and the Shapiro–Loginov formula, the exact expression for the output spectral amplification (SPA)...

We investigate the entropic stochastic resonance (ESR) in a confined system, subject to dichotomous noise and white noise, driven by a periodic square-wave signal, by a constant force along the x-axis of the structure as well as by a constant force in the transversal direction. Under the...
