| Abstract | ||
| In the present work, the chaotic signal that produces experimentally was studied by using Lorenz model. Nonlinear behavior (chaotic) in a nonlinear device was created using a Lorenz circuit. The dynamical system can be perceived by using the bifurcation diagram. In order to encode the message to the chaotic carrier signal, Lorenz circuit has been used. The decoding of the message is achieved by the synchronization between the chaotic oscillator of the transmitter and the receiver. This work studied the change of time series of the chaotic signal with changing the initial conditions where the stochastic parameters areσ=10, R=30, and b=8/3, while initial conditions are Xint=yint=zint=0.01, x1=0.03, and yint=zint=0.01. | ||
