Aim:
After passing the course, the student should
- be generally aquainted with modern telecommunication, i.e. be able to briefly describe several telecommunication techniques, especially concerning channel sharing and mobile telephony.
- be able to briefly account for some common channel models, especially for cables and radio channels.
- be able to describe problems that arise in telecommunication situations, using own words, and be able to describe, and in a relevant way, compare methods to counteract those problems.
- be able to reliably perform standard calculations regarding digital modulation, binary (linear) codes for error control and source coding.
- be able to, with some precision, analyze and compare various choices of digital modulation methods and coding methods in terms of error probabilities, minimum distances and related concepts.
- be able to account for the connection between different concepts in the course in a structured way using adequate terminology.

The exam consists of three parts:
- One introductory task that examines the learning outcome " be able to reliably perform standard calculations...". This task has to be solved correctly in order to pass the exam.
- A question part, with questions of descriptive or investigative character. This part examines the learning outcomes " be generally aquainted with...", "be able to briefly account for...", "be able to describe problems..." and "be able to account for the connectionâ?¦". Separate demands on the number of points in this part to pass.
- A problem part, that examines the learning outcome " be able to, with some precision, analyze and compare...". Separate demands on the number of points in this part to pass.
The grade is based on the total number of points obtained on the exam.
