  When two systems are coupled, one can play the role of the driver, and the
other can be the driven or response system. In this scenario, the driver system
can behave as an external forcing. Thus, we study its interaction when a
periodic forcing drives the driver system. In the analysis a new phenomenon
shows up: when the driver system is forced by a periodic forcing, it can suffer
a resonance and this resonance can be transmitted through the coupling
mechanism to the driven system. Moreover, in some cases the enhanced
oscillations amplitude can also interplay with a previous resonance already
acting in the driven system dynamics.
