Aims:
To engender specialist knowledge and understanding of telecommunications transmission theory and principles. To develop advanced mathematical skills in relation to telecommunications signals and an understanding of time and frequency domain representations. To be able to evaluate non-deterministic signals through their probability distribution.

Learning Teaching & Assessment Strategy:
The factual basis, concepts and principles of the subject will be introduced through formal lectures in which routine derivations and analysis will be demonstrated. The material is re-enforced through whole-group seminars. Tutorial exercises, recommended texts and the lecture notes provided, enable students to consolidate what they have learned. Students may self-assess by comparing their tutorial solutions with worked solutions provided.

Laboratory sessions permit students to explore how the principles are applied in practice and to re-enforce their understanding.

The `open-logbook` coursework test provides an opportunity to evaluate student`s understanding of the material explored in the laboratory and is important because it enables quantitative interim feedback to be provided to students.

In the remaining time, students have the opportunity to reflect on, explore and extend their knowledge and understanding and to prepare for the formal examination.

The supplementary examination will test knowledge and understanding of material covered in both lectures and laboratory sessions.
