DRIVING AND SYNCHRONIZING BY CHAOTIC IMPULSES

For a class of dynamical systems driven by chaotic impulses we give co nditions for the occurrence of chaos locking. It is shown how the. con cept of time-discontinuous coupling of two chaotic systems may lead to generalized synchronization. The method of synchronization is interpr eted as a nonlinear analog of the sampling theorem. Furthermore, we ex amine the effect of amplitude quantization of the driving signal on th eir synchronization. Even though two time-discontinuously coupled dyna mical systems are no more exactly synchronized when the driving signal is digitized, their trajectories are close enough to allow correct tr ansmission of digital information signals between them.
