CORE DEFINITION

Stochastic resonance (SR) is a mathematical mechanism and behavior of nonlinear systems (that is, systems in which the change of the output is not proportional to the change of the input) where random (stochastic) fluctuations in the microstate of a system (that is, its specific configuration, including the precise positions and momenta of all its individual particles or components) cause determin

In certain nonlinear systems, an appropriate amount of noise can actually enhance the detectability of weak signals, allowing the signal and noise to synergistically improve the output signal-to-noise ratio.
