Radio Transmitters and Receivers

The course is a substitute for:

Radio Transmitters and Receivers (D37RVP)

Lecturer:

Tutor:

Supervisor:

Department of Radioelectronics

Synopsis:

The subject RTR makes students familiar with basic blocks and systems of radio transmitters and receivers. Lectures cover analog and digital systems in the whole range of radio frequencies. Because of application character of the subject, good knowledge of electronic devices, circuits and theory of signals and RFB is assumed. 85 % of the exercises is realised as the laboratory measurements.
