EXPERIMENTAL CHAOS FROM AUTONOMOUS ELECTRONIC-CIRCUITS

Autonomous electronic circuits provide a convenient framework in which to study chaotic phenomena. These systems are easy to build, easy to measure, and easy to model using differential and difference equations . Furthermore, they operate in real time, and parameter values are rea dily adjusted. In this work, are discuss the nature of chaotic steady- state behaviour and describe how it manifests itself in autonomous ele ctronic circuits. We study state space, time- and frequency-domain mea surement techniques for characterizing steady-state behaviour. Because of its value as a paradigm for exploring chaos, we choose Chua's osci llator as the vehicle for our experiments.
