Module summary

Computers, phones, and almost every electronic device on the planet make use of digital circuits. This module introduces the operation of digital logic circuits in a variety of applications, and tools and techniques for their design and analysis, drawing examples from a personal computer. The labs reinforce theoretical concepts through design, simulation, building and measurement of digital circuit blocks using discrete integrated circuits and a programmable logic device.

Module feedback

'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme.  We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments.

A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback.  This can be found at

The Department of Electronic Engineering aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme.  In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work.  Students are provided with their examination results within 20 working days of the end of any given examination period.  The Department will also endeavour to return all coursework feedback within 20 working days of the submission deadline.  The Department would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback.  The Department will endeavour to keep such delays to a minimum.  Please note that any marks released are subject to ratification by the Board of Examiners and Senate.  Meetings at the start/end of each term provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date. 

Indicative reading

Notes and readings will be provided in class.

The information on this page is indicative of the module that is currently on offer. The University is constantly exploring ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary by the University. Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.
