Response of chaotic spiking circuit to periodic/nonperiodic inputs

This paper studies response of a chaotic spiking circuit to spike-train inputs. Applying input, chaotic behavior is changed into a variety of phenomena and we introduce two interesting phenomena. The first one is "chaos + chaos = order": mixing two periodic inputs each of which causes chaos, the circuit exhibits periodic phenomena. The second one is "consistency": applying some kind of random input, the circuit exhibits identical nonperiodic steady state response for various initial states. We derive return map and analyze these phenomena precisely.
