Summary of the subject: In the process of teaching the discipline, the principles of construction and operation of radio and television systems and devices are considered. The features of the schematic implementation of individual nodes of radio and television devices are considered. Significant attention is paid to the study of the features of the construction and operation of digital radio and television systems of the DAB and DVB standards. The physical foundations of television are considered, the main systems of analog color television are reviewed, and the prerequisites for the transition to
of digital television, as well as the relationship between the parameters and characteristics of analog and digital television.
