GENERALIZED SYNCHRONIZATION OF CHAOS IN ELECTRONIC-CIRCUIT EXPERIMENTS

Two examples of one-way coupled electronic circuits displaying general ized synchronization of chaos are considered. In one of them, the dyna mics of both the response and the driving systems represent a double-s croll chaos oscillator. In another example, the double-scroll oscillat or is driven by an electronic analog of the Mackey-Glass system. To de tect the generalized synchronization, an auxiliary response system tha t is a replica of the original one is used. In these systems, we have discovered two types of generalized synchronization, namely, a strong and a weak synchronization, which correspond to the existence of a smo oth and a nonsmooth map from the trajectories of the driving attractor to the trajectories of the response system, respectively.
