In our technologically-oriented world we need to process, interrogate and manipulate ever-increasing amounts of data from a wide variety of sources - such as video, audio and text, information databases, sensors and measurement systems, manufacturing equipment and robotic systems etc. Today, such signal processing is invariably carried out using digital techniques, and so digital signal processing (DSP) has become an invaluable and integral part of a wide variety of fields ranging from consumer electronics to medicine to space exploration. In this module you learn about the theory that lies behind the enormous popularity and power of DSP, as well as learning how to design and implement real-world DSP systems.

Prerequisite module: ECM1102, ECM1106, ECM2115, ECM2118 or equivalent
 

This module introduces you to the fundamental principles of digital signal processing, from both theoretical and practical viewpoints. You will get the chance to design digital signal processing systems for a range of important application areas, and to develop experimental digital signal processing applications using the XiLinx FPGA devices.

This is a constituent module of one or more degree programmes which are accredited by a professional engineering institution under licence from the Engineering Council. The learning outcomes for this module have been mapped to the output standards required for an accredited programme, as listed in the current version of the Engineering Council’s ‘Accreditation of Higher Education Programmes’ document (AHEP-V3).

This module contributes to learning outcomes: SM1p, SM2m, EA1p-EA3p, EA1m-EA3m, D2p, D2m, D3p, D3m, EP1p, EP1m, EP2p, EP2m, EP4p, EP4m, EP9p, EP11m, G1p, G1m

A full list of the referenced outcomes is provided online: http://intranet.exeter.ac.uk/emps/subjects/engineering/accreditation/

The AHEP document can be viewed in full on the Engineering Council’s website, at http://www.engc.org.uk/
