Learning outcomes of the course unit

Students will be introduced in detail to data transmission systems and the possibilities of realizing data communication in these systems. The subject matter discussed is focused mainly on codes, their types and their application. Based on the range of the subject matters the student should be able, after a successful completion of the course, to solve all the standard problems that appear in this type of data communication.

Prerequisites

The subject knowledge on the secondary school level is required.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Not applicable.

Assesment methods and criteria linked to learning outcomes

A precondition for awarding the credit pass is a successful completion of laboratory measurements and computer practice. The student can miss 20% of practice if properly excused. The missed practice must be made up for by agreement with the instructor.
