Simulation of circuits demonstrating stochastic resonance

GP Harmer, D Abbott - Microelectronics Journal, 2000 - Elsevier
In certain dynamical systems, the addition of noise can assist the detection of a signal and
not degrade it as normally expected. This is possible via a phenomenon termed stochastic …
