FEEG1004 Electrical and Electronics Systems

Module Overview

It is difficult to imagine what the world would be like without electricity: homes without electric light, without television or radio, without motors to drive the washing machine, the refrigerator and the vacuum cleaner; offices without computers, word processors, telephones and photocopiers. It is almost impossible to think of a railway system without electric signalling and control or a factory production line without electric drives. Wherever we turn we see electricity at work distributing energy, transmitting information, and controlling every conceivable process. While it is certainly possible to build a mechanical system (mechanisms or machines) with mechanical components only (e.g. early steam engines, boats and aeroplanes), it is more common to see mechanical systems comprising a mix of mechanical and electrical components or mechatronic systems. Modern cars, boats, aeroplanes, robots and digital cameras are good examples. Learning the subject of electricity is therefore vital to all engineering disciplines including mechanical engineering, aeronautics and astronautics engineering, acoustic engineering and ship science. Not only that a mechanical/aero/astro/acoustic/ship Engineer need to be able to communicate with other electrical and electronic engineers in a multidisciplinary project he/she will often find themselves having to actually design or operate the electrical or electronic subsystems. The aim of this module is to introduce the subject of electricity and electrical systems focusing on the fundamentals of the subject in the context of applications in the areas of mechanical, aero, acoustic and ship engineering. These application areas are primarily in the areas of measurement and control. The fundamentals introduced in this module will be built on by other subjects such as advanced modules on electrical and electronic systems, measurement and instrumentation modules, avionics and control system modules. Additionally, some of the mathematical techniques applied to circuit analysis are also applicable to the analysis of heat transfer problems, mechanical system dynamics, fluid flow in pipes and others

Learning and Teaching

Teaching and learning methods

• Lectures for the whole class • Feedback Workshops (Tutorials) for small groups. • laboratory sessions - Oscilloscopes, waveforms and filters experiment - Familiarisation oscilloscopes and signal generators. Measurement of frequency response of low pass and high pass RC filters. Use of diodes to produce full wave and half wave rectification. - Operational amplifiers and Logic circuit experiment - Familiarisation with op-amps, use of op-amps as amplifiers, comparators, zero crossing detectors and summers. Learning activities include • Self-study • Solving example sheet problems • Solving assignments Relationship between the teaching, learning and assessment methods and the planned learning outcomes In the lecture sessions, basic theory is explained and illustrated by example, with references to relevant applications. The students learn the material by attempting to solve the tutorial sheets, which are also discussed during the Feedback Workshop (Tutorial) sessions. At the end of each workshops the students submit a solution to one of the problems. These are marks and returned with feedback comments at the start of the following workshop. In the laboratory session the students learn how to use the different instruments and how to build simple electric circuits. They write a report that briefly describes the experiment, presents and discusses the results. The report is assessed and feedback is given to the students. The students are assessed by a 1 hour mid-sessional test in January/February, and 2 hour examination at the end of the course in May/June. Feedback is given on the script of the mid-sessional test, which is returned to the students. Feedback on the final exam is given through the final mark. Students also have the opportunity to view their exam script, if they wish.
