Abstract

In this brief, an all-digital chaotic operating electronic circuit, which is suitable for information modulation and chaotic transmission, is introduced. The chaotic oscillating circuit is a nonautonomous one, and it is designed in such a way that signals at all stages are digital ones. No analog subcircuit is involved in generating chaos. Oscillator design and experimental demonstration of its chaotic behavior are provided, together with the evaluation of the chaotic properties that it possesses, employing established nonlinear dynamics tools.
