| Hi-index | 0.00 |
In this paper we have studied experimentally the case of chaotic synchronization of two identical nonlinear electric circuits. This is a very interesting research area because of its applications to the field of secure communications. The circuit we have used is a second order, Duffing-type, nonlinear electric circuit driven by a sinusoidal voltage source. The nonlinear element has a cubic i-v characteristic of the form, i(v) = p ċ v + q ċ v3. We have studied the dynamic behavior of the system in the case of the bidirectional coupling via a linear resistor. Both experimental and simulation results have shown that chaotic synchronization is possible.
