Supervisor:

Department of Radioelectronics

Synopsis:

The subject RTR make students familiar with basic systems, blocks and circuits of radio transmitters and receivers. Lectures cover analog and digital systems in the whole range of radio frequencies. Good knowledge of electronic devices, circuits and theory of signals is desirable for successful studies of the subject. The exercises are in the laboratory.
