Supervisor:

Department of Radioelectronics

Synopsis:

The aim of RFB subject lectures is to make students familiar with basic features, parameters and design of radio transmitters and receivers blocks and circuits. The exercises deal with basic calculations in this field. They are completed with PC simulations. They take place in the second half of the semester.

Requirements:

No prerequisities.
