Signals and systems. Exercise materials for exercises

The script presents the basics of description and analysis of signals and systems that process signals both continuous and discrete in time, determined and random. In addition to the classic Fourierian representations, time-frequency techniques are discussed. A significant part of the script was devoted to the methods of modeling signals and systems, parameter estimation and simulation algorithms. Additionally, the elements of the theory of detection of useful signals against the background of disturbances are presented. Each chapter contains problems and tasks for self-solution.
