Movement of small amplitude parts in a coupled chaotic system

We investigate the movement of small amplitude parts in a coupled chaotic system. The system consists of chaotic circuits using CMOS ring oscillators and capacitors as coupling elements. In the case of coupling 25 chaotic circuits, irregular movements of small amplitude parts are observed for the same parameter and different initial values. This is a kind of spatio-temporal phenomena. We focus attention on difference of the movement. Distributions of the small amplitude parts are investigated.
