Suprathreshold Stochastic Resonance in a Single Comparator
Wang Ren-Guo1 and Long Zhang-Cai1
Show affiliationsStochastic resonance usually appears when stimulus is too weak to overcome barriers in a nonlinear system. Unusually, we demonstrate that in a simple comparator as a prototype model, stochastic resonance can still occur when the stimulus is predominantly suprathreshold. This result provides new knowledge for understanding of mechanism underlying information process in biological systems and also finds applications in signal processing.
