Suprathreshold stochastic resonance

From Wikipedia, the free encyclopedia

Suprathreshold stochastic resonance is a particular form of stochastic resonance, that is, the phenomenon where random fluctuations, or noise, provides a signal processing benefit in a nonlinear system. Unlike most of the nonlinear systems where stochastic resonance occurs, suprathreshold stochastic resonance occurs not only when the strength of the fluctuations is small relative to that of an input signal, but occurs even for the smallest amount of random noise. Furthermore, it is not restricted to a subthreshold signal, hence the qualifier, suprathreshold, in suprathreshold stochastic resonance.
