Abstract: The mechanisms of information transmission are investigated in a lattice of coupled continuous maps, by analysing the propagation of both finite and infinitesimal disturbances. Two distinct regimes are detected: in the former case, both classes of perturbations spread with the same velocity; in the latter case, finite perturbations propagate faster than infinitesimal ones. The transition between the two phases is also investigated by determining the scaling behaviour of the order parameter.
