Система передачі інформації за допомогою генератора детермінованого хаосу на основі кільцевої схеми з 2,5 степенями свободи

Abstract

The master's qualification paper presents the results of the development and research of a system of information transmission using a generator of detected chaos based on a circular scheme with 2.5 degrees of freedom. In the theoretical part an analysis of the current state of the basis of the theory of deterministic chaos and information was conducted. The electrical structural and functional scheme of the device is developed. The study of dynamic processes in a generator of deterministic chaos in a bipolar transistor structure with negative resistance is performed. In the experimental part of master's qualification work the results of computer modeling of the use of the generator of deterministic chaos in the direct-chaotic system of information transmission are presented. The facsimile portraits of deterministic chaos generators based on a circular scheme with 2.5 degrees of freedom, time and frequency characteristics of the generated chaotic signals are given. In this work, calculations of the economic part, as well as labor and safety in emergency situations have been carried out.
