# Noise, Waves & Fields - ELE00034I

« Back to module search

• Department: Electronic Engineering
• Module co-ordinator: Dr. John Dawson
• Credit value: 20 credits
• Credit level: I
• Academic year of delivery: 2021-22

## Module summary

The Noise Fields and Waves module provides essential content for the design of analogue and digital circuits, by considering: the effects of noise and interference on circuit performance along with the basic concepts of electromagnetic compatibility. It introduces transmission line effects on interconnects such as delay, reflections, and crosstalk, which are important considerations in any high speed digital circuit and in transmission of signals over cables. The electromagnetic theory of fields and waves is analysed in order to underpin the theory of transmission lines and provide the foundations for later courses in radio frequency circuits, antennas, wireless propagation, nanotechnology, and semiconductor device design.

## 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 https://www.york.ac.uk/students/studying/assessment-and-examination/guide-to-assessment/

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.
