Course detail

Radio Receivers and Transmitters

FEKT-CRPVAcad. year: 2019/2020

Students become familiar with architecture of analogue and digital radio-communication systems (block scheme, basic functions). Further, the function of analogue and digital circuitry used in radio-communication systems (amplifiers, oscillators, mixers, filters, modulators, demodulators, etc.) are described. At the end the students obtain basic information about recent radio broadcasting systems (FM, DAB, DRM).

Learning outcomes of the course unit

The graduate is able (1) describe architecture of common analog and digital radio-communication systems, (2) explain function of selected analogue and digital circuitry used in radio-communication systems, (3), and orientate oneself in techniques used in recent radio broadcasting systems.


Fundamentals of signal processing and theory of electronic circuits are required.
