Experimental study on chaotic synchronisation with non-ideal transmission channel

In this paper some new experimental results about synchronisation of chaotic circuits coupled by a non-ideal transmission channel are reported. In particular, the case of two Chua's oscillators, realised by state controlled cellular neural networks (CNNs), and synchronised by using the inverse system approach has been considered. Two different studies have been carried out. In the first one, the effects of coupling the two systems by using a coaxial cable have been investigated by simulation. In the second one, the effects of adding noise and disturbances to the coupling signal in a real experimental set-up have been considered.
