Definition
Originally discovered in climate data (Nicolis and Nicolis 1981; Nicolis 1982), the phenomenon of stochastic resonance occurs when an intermediate (i.e., neither too large nor too small) amount of noise enhances the transmission of a weak periodic signal (McNamara and Wiesenfeld 1989). More specifically, the signal-to-noise ratio of the weak periodic signal is increased by the added noise; the signal is “weak” in the sense that, in the absence of noise, it is below the threshold of detection. A low-amplitude added noise contributes jitter to the weak periodic signal, but is not sufficient to ever push the signal over the detection threshold. A large-amplitude noisy input, in contrast, adds so much jitter that, while the weak signal plus noise does often exceed the threshold, the signal is not separable from the noise (Jung and Hänggi 1991; Dykman et al. 1992). An intermediate-amplitude noisy input allows the weak...
