Generation of Chaos using a simple electronic circuit

Chaos is a behavior that is not periodic, apparently random, where the system response is still recurrent, but no longer in a predictable way. A non-linear system with an electronic feedback can show bistable behaviour and may produce chaotic response. Chaotic signal can be utilized for secure encryption of a communication system. In this paper, we have designed a novel simple electronic circuit to obtain a chaotic transfer function of nature Sin²X. We also have demonstrated the mathematical modelling of the circuit and have made it chaotic by varying system bias and parameters using MATLAB. The circuit is designed in lab and output is obtained using digital storage oscilloscope.
