It is well known that chaotic signals are characterized by having a positive Lyapunov exponent and a noise-like power spectrum [Young, 1983]. These features have motivated researchers to investigate using chaotic signals in various applications and particularly in wide-band communication systems [Kolumbán et al., 1998; Setti et al., 1999]. In order to be compatible with other system elements, i...

In recent years, the standard Cellular Neural Networks (CNN’s) introduced by Chua and Yang [1988] have been one of the most investigated paradigms for neural information processing. In a wide range of applications, the CNN’s are required to be completely stable, i.e. each trajectory should converge toward some stationary state. However, a rigorous proof of complete stability, even in the simple...

The Chua circuit, known to exhibit chaotic behaviour, has been constructed and studied. The goal was to investigate the experimental underpinning of the theory. The component relationship of the resistors, capacitors, inductors and operational amplifiers have been measured and established within their domain of validity. The system equations themselves cannot be directly validated through a tra...

CNN were first proposed by Chua and Yang [1988a, 1988b]. Since then much work has been done in the electricial engineering community, e.g. [Chua & Roska, 1993; Thiran et al., 1995]. The main applications of CNN are in image processing and pattern recognition, see [Chua, 1998]. A basic and important class of solutions of (1) are the stable stationary solutions of (1). It plays an important role ...

Experimental phase synchronization of chaos is demonstrated for two different chaotic oscillators: a plasma discharge and the Chua circuit. Our technique includes real-time capability for observing synchronization-desynchronization transitions. This capability results from a strong combination of synchronization and control, and allows tuning adjustments for search and stabilization of synchron...
