An experimental board is discussed in this paper, in which pattern formation and active wave propagation phenomena can be observed. In particular, the CNN paradigm has been considered for the rules which drive connections among circuits in the whole frame. It is therefore organized as a CNN array of 25 cells arranged into a matrix of dimesion 5×5, where each cell is a second-order non-linear system characterized by a piecewise linear output non-linearity. Calculations and experiments are compared in order to see that such spatio-temporal phenomena can take place in arrays of non-linear second-order circuits locally connected, strictly resembling what obtained in simulations, in spite of noise arising from a real analog frame. © 1998 John Wiley & Sons, Ltd.
