Tutor:

Josef Dobeš, Pavel Puričer, Karel Ulovec

Supervisor:

Department of Radioelectronics

Synopsis:

The purpose of the subject is acquiring fundamental knowledge of related themes of communication and electronics. First, the students are introduced to fundamentals of communication, the most important analog and digital modulations, and basic conception of radio systems. Second, students give information about basic elements, connections, and function blocks of electronics. The last part of the subject is devoted to explication of fundamental circuits of radio engineering.
