Requisites
Pre-requisite: (ELE2504 and ELE2601) or Students must be enrolled in one of the following Programs: GCEN or METC or MEPR or MENS or GCNS or GDNS
Overview
Most modern electronics incorporate some degree of communication into their design. As such a foundational understanding of the many technologies and methodologies used to create these communication systems is required. The purpose of this course is to provide an introduction to these specialised techniques and their related hardware and software components, and to study modern analog and digital communication systems and their utility in modern electronics design. This course follows on from ELE2601 and ELE4605 and leads into ELE4607.
Students will gain an appreciation to the methods used to create communication systems across three broad areas of techniques and methods; systems and components; and real world applications. Students will study a wide range of relevant communication topics including phase locked loops, noise, modulation methods, electromagnetic propagation, antennas and optical fibre communication. The utility of these topics is illustrated by reference to existing communication systems such as telephone networks, TV/DTB, modern cellular mobile systems, microwave radio, radio navigation aids, and satellite communication systems.
Course learning outcomes
The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:
- demonstrate an awareness of standards such as CCIR and CCITT recommendations;
- calculate the performance of simple communications circuits;
- calculate the propagation characteristics of electromagnetic waves in free space and in the troposphere;
- analyse the performance of simple aerials and aerial arrays;
- analyse the structure and identify the relationship between various subsystems in modern communication systems.
