Abstract: We investigate Coherence Resonance phenomenon in an electronic circuit obeying the FitzHugh-Nagumo dynamics. The phenomenon is induced with a noise source exhibiting different nature. The resonance behavior results are significantly reinforced when experimental parameters are tuned in order to place the stable fixed point closer to the excitability threshold of spiking behavior, as well as when the time scales of the circuit are properly modified.
