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.
