Lecturer:

Pavel Kovář

Tutor:

Pavel Kovář, Jaroslava Horevajová, Petr Kačmařík, Pavel Puričer, Josef Špaček, Karel Ulovec

Supervisor:

Department of Radioelectronics

Synopsis:

The subject KTRS makes students familiar with basic principles of radio communication, communication channel features and describes communication and navigation systems. Lectures cover analog and digital systems in the whole range of radio frequencies. 50 % of the exercises is realised as seminars and 50 % is realised as laboratory measurements on transmitters, receivers and their function blocks.
