Lectures provide core material and guidance for further reading. Problem solving is introduced through lectures and practised during tutorial sessions. Laboratory sessions provide an opportunity to gain practical experience of the application of techniques introduced during lectures
The format of resits will be determined by the Board of Examiners
|Prob solv exercises||2||M||15||2 problem solving exercises for signals and communications respectively. Each exercise is worth 7.5%.|
|Practical/lab report||2||M||15||Completion of a notebook for lab report preparation worth 3% and two lab reports woth 6% each.|
The examination provides the opportunity for the students to demonstrate their understanding of the course material. The problem solving aspects of the examination and of the assignment enable the students to demonstrate that they are able to apply this understanding and their analysis and synthesis skills to specific problems. The laboratory report provides the opportunity for the students to demonstrate an in-depth understanding of selected topics.
