Title
Response of coupled chaotic circuits to sinusoidal input signal
Abstract
In this study, synchronization state of the coupled chaotic circuits is investigated when a sinusoidal input signal is added by both of computer simulations and circuit experiments. It is confirmed that the synchronization state changes by the values of the amplitude and the angular frequency of the input signal. 1. INTRODUCTION Studies on engineering applications of chaos, such as chaos communication systems and chaos cryptosystems, attract many researchers' attentions. Since, theoretically speak- ing, chaotic signals possess infinite information, it could be possible to create novel engineering systems with great ad- vantages. However, at this moment, there have been few systems with some kinds of advantages over conventional engineering systems. Hence, basic researches on chaotic phenomena with future engineering applications in mind are still quite important. In this study, we investigate synchronization phenom- ena of two chaotic circuits coupled by a resistor when an input signal is added. Because the circuit tends to minimize the current through the coupling resistor in such a coupled system (1)-(3), synchronization phenomena change to com- pensate the effect of the input signal. More concretely, we use a sinusoidal signal with the averaged amplitude and the averaged frequency of the chaotic signals as a standard in- put signal. We investigate the synchronization phenomena when the amplitude or the frequency of the sinusoidal input signal is varied. The results suggest that coupled chaotic circuits could be utilized to extract some kinds of features of unknown input signals.
