Chaotic oscillator based on delay line

Abstract

A novel chaotic oscillator with time delayed feedback is described in this paper. The oscillator is based on simple nonlinear circuit, gain stage and delay line. Chaotic systems are characterized by an extreme sensitivity to initial conditions. In this paper, instead of initial condition, the initial input wave (or voltage) is used. For chaotic system control also the gain of the amplifier is changed for different signal on output. Therefore for some values of gain, the output is periodic - non chaotic, but can be changed to chaotic when gain is increased. The behavior of chaotic oscillator was simulated as electronic circuit and results of simulations are presented. This oscillator can be used in different applications where chaotic - non chaotic behavior is important, e.g. generators, encryptions etc.
