Abstract :
The propagation of a periodic wave over a nonlinear line of two-state threshold elements is considered. A theoretical model and an experimental realisation confirm that the propagation of a low-amplitude wave can be improved by the addition of noise. This represents a new instance of the nonlinear phenomenon of stochastic resonance for signal enhancement by noise.
