Fabing DUAN - La résonance stochastique.

NOISE IS GOOD

Residual aperiodic stochastic resonance and its applications in signal transmission, detection and neuron information processing.

Aperiodic stochastic resonance (ASR) is first observed to emerge in a single bistable system driven by a supra-threshold binary signal. This new form of ASR is termed residual ASR. Residual ASR is a temporal effect wherin the system response to a relatively fast supra-threshold input is expedited by noise. This effect is a novel use of noise, especially in the situation where the system dynamical switching time is non-negligible.
