Timing and Structure
7 lectures: 1 in week 5, 2 per week in weeks 6-8
The aims of the course are to:
- Introduce the basic elements of typical communication systems.
- Provide an understanding of bandwidth, as it applies to signals and transmission channels.
- Discuss digitisation of signals and how it affects their properties.
- Understand the basic elements of analogue and digital modulation schemes.
As specific objectives, by the end of the course students should be able to:
- Describe the key elements of a communication system.
- Understand analogue modulation, and discuss the merits of amplitude and frequency modulation, and their power and bandwidth requirements.
- Understand how digitisation affects the characteristics of a signal; in particular, the separate effects of sampling (in time) and quantisation (in amplitude).
- Analyse the trade-off between quantisation rate and the quality of digital representation.
- Understand the basic principles of digital modulation, be familiar with the design choices involved, and analyse the performance of modulation schemes in terms of error probability and data rates.
- Understand the need for coding, and encode and decode bits using simple error-correcting codes such as repetition and Hamming codes

The UK Standard for Professional Engineering Competence (UK-SPEC) describes the requirements that have to be met in order to become a Chartered Engineer, and gives examples of ways of doing this.
UK-SPEC is published by the Engineering Council on behalf of the UK engineering profession. The standard has been developed, and is regularly updated, by panels representing professional engineering institutions, employers and engineering educators. Of particular relevance here is the 'Accreditation of Higher Education Programmes' (AHEP) document which sets out the standard for degree accreditation.
The Output Standards Matrices indicate where each of the Output Criteria as specified in the AHEP 3rd edition document is addressed within the Engineering and Manufacturing Engineering Triposes.
