Module Overview

A biomedical engineer must have a qualitative understanding of the importance of biomedical signal processing. Furthermore, the student should be able to apply fundamental signal processing concepts quantitatively to biomedical engineering problems. This module builds a basic understanding of signal processing concepts relevant to biomedical engineering.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate understanding of biomedical signal processing methods as well as the ability to analyse time-domain and frequency-domain characteristics of different biomedical signals. The first coursework assignment allows students to demonstrate their knowledge and understanding of basic time-domain and spectral signal processing techniques. The second coursework assignment allows students to demonstrate their knowledge and understanding of filters, time-frequency and non-linear signal processing techniques. Both coursework assignments also test report writing skills as well as the students’ ability to comment critically on their results. The final examination tests the deeper understanding of the different biomedical signal processing methods presented in the module, including open-ended questions asking the students to come up with possible signal processing options for real-life biomedical engineering problems.

Thus, the summative assessment for this module consists of:

  • Coursework 1 [Learning outcomes 1, 3, 4, 6]       (20 hours)            Deadline W7   {20%}

  • Coursework 2 [Learning outcomes 1, 2, 3, 4, 6]   (25 hours)            Deadline W12 {25%}

  • Examination   [Learning outcomes 1, 2, 3, 4, 5]   (2 hours)                                     {55%}

Formative assessment and feedback

  • Formative verbal feedback is given in tutorials

  • Formative Multiple Choice Tests are available on SurreyLearn to give feedback on the understanding of biomedical signal processing techniques

  • Extensive written feedback is given on the coursework assessments

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Introduce basic biomedical signal processing principles through theory with worked examples. This is delivered principally through lectures and tutorial classes. In the latter, students will have to write Matlab scripts and functions for the analysis of biomedical signals. Learning would be reinforced with the application of the biomedical signal processing principles to real biomedical signals in two coursework assignments.

The learning and teaching methods include:

  • 2 hours lecture per week x 11 weeks

  • 2 hour Matlab-based tutorials x 11 weeks

  • 2 hours revision lecture

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
