FUNDAMENTALS OF DIGITAL SIGNAL PROCESSING - 2024/5

Module Overview

Expected prior learning: Knowledge of basic properties of signals and related methods, including Fourier series, Fourier transforms, Laplace transforms, and convolution. BEng/MEng students might have acquired this through study of module EEE2035 Engineering Mathematics III and/or module EEE2033 Circuits, Control and Communications. MSc students might have acquired this through study of an undergraduate module on “Signals and Systems” or through independent study.

Module purpose: This introductory course in Digital Signal Processing explores mathematical tools used to represent, analyse and design basic DSP systems. This module underpins many key areas of digital systems, including audio-visual technology, digital communications, control systems, and computer vision. This topic is therefore of paramount importance to any electronic engineer.

This module EEE3008 provides the expected prior learning for the following module EEEM030 Speech & Audio Processing and Recognition

Taking module EEE3008 may also contribute to a deeper understanding of the following modules EEE3032 Computer Vision and Pattern Recognition, EEE3042 Audio and Video Processing and EEEM071 Advanced Topics in Computer Vision and Deep Learning

Assessment Strategy

The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the skills and knowledge as described in the learning outcomes. The written examination will assess the knowledge of terminology, concepts and theory of digital signal processing, as well as the ability to analyse problems and apply mathematical models of signal processing to solve and predict effects. The laboratory experiments will evaluate the acquired technical skills and expertise required to apply these methods to practical signal processing tasks.

Thus, the summative assessment for this module consists of the following:

Coursework: Laboratory experiments concerned with analysis and design of signal processing systems

Exam: Written examination.

Formative assessment and feedback 

For the module, students will receive formative assessment/feedback in the following ways:

During lectures, by question and answer sessions;

During tutorials/tutorial classes;

During supervised laboratory sessions;

During meetings with lecturers and tutor.

Module aims

• Equip students with a thorough understanding of core DSP concepts and methods,
• Enable students to analyse discrete signals,
• Enable students to design discrete systems and
• Enable students to analyse more complex signal processing applications in the future.
• The module also aims to provide opportunities for students to learn about the Surrey Pillars listed below.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to achieve the specified learning outcomes by teaching the module syllabus in lectures, and supporting the assimilation and understanding of the taught material via tutorial classes. The practical design and technical skills related to the subject are acquired through coursework involving the investigation and application of digital signal processing methods via laboratory experiments.

Learning and teaching methods include:

Lectures

Tutorials

Lab sessions

Revision tutorials

Captured content

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.

Other information

Surrey's Curriculum Framework is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills and capabilities in the following areas:

Digital capabilities: Students will develop skills in digital signal processing, which is a key digital technology in electronic engineering. They will gain practical skills and experience in digital signal processing through coursework exercises in lab sessions using the MATLAB programming language.

Employability: This module provides foundational skills in digital signal processing, including understanding and analysing digital signals, digital filter design, and sample rate conversion. These are important topics with a wide range of industry applications such as image and video processing, speech processing, digital communications, and artificial intelligence.

Global and Cultural Capabilities: Digital signal processing systems, and the underpinning mathematics used to describe and analyse them, are used globally, so the know-how developed in this module can be applied anywhere in the world. The students taking this module are from a diverse background and from a host of nationalities and cultures, thus in-class discussions in tutorials and lab sessions provide opportunities for students to broaden their horizon with a global perspective.

Sustainability: This module includes consideration of issues of efficiency in signal processing, including designing filters of appropriate sizes to achieve required performance, which are important for sustainable use of computing hardware and software resources.

Resourcefulness and Resilience: This module develops student skills in using the digital signal processing theory they have learned in lecture material to solve exercises in tutorial sheets, to answer questions in written examinations, and to analyse problems and design solutions in computer labs.
