Abstract
In this paper, simulation and hardware implementation of the device for generating chaotic signals based on logistic mapping using microcontrollers of the РІС18 series was carried out. The operation of the device was investigated in the mode of generating chaotic oscillations at different values of the control parameter λ. By certain hardware and software modification, this generator can be used as a voice signal encryption The results of simulation and experimental studies confirm the possibility of using PIC18 microcontrollers for the implementation of chaotic oscillation generators based on discrete mappings, as well as using these controllers in the hardware implementation of language information encryption devices.
