EXCITATION OF A POTENTIALLY SELF-OSCILLATING STATE IN AN OSCILLATOR WITH DELAY AND INERTIA EXPOSED TO THE SIMULTANEOUS ACTION OF REGULAR AND CHAOTIC SIGNALS

An analysis is made of the possibility of inducing a potentially self- oscillating state in a bistable self-oscillating system exposed simult aneously to regular and chaotic signals, as applied to the covert tran sfer of information in a binary computational system. A system of nonl inear differential difference equations is derived, which describe the behavior of an oscillator with delay and inertia under the action of complex oscillations in a given time interval. It is shown numerically that even when a potentially self-oscillating state is not excited by an external regular signal, stochastic oscillations, as well as provi ding a masking effect, may function as an additional stimulus to trans fer the system to the basin of attraction of a potentially self-oscill ating attractor.
