The course deals with transmission systems (TS) at an advanced level. It includes the theoretical analysis of TS as well as their practical implementation. In the laboratory, students are trained in the practical skills in the area of TS. The following topics are discussed: noise and its influence on transmission quality, regeneration of digital signals, baseband line codes, passband line codes, clock extraction and timing, xDSL technologies.
