What is it all about? Electrical and Electronic Engineering is an exciting and dynamic field. Electrical engineers e ngineers are responsible for the generation, transfer and conversion of electrical power, while electronic engineers are concerned with the transfer of information using radio waves, the design of electronic circuits, the design of computer systems and the development of control systems such as aircraft autopilots. These sought-after engineers can look forward to a rewarding and respected career. What we do about it Electrical energy systems - encompass the study and design of electrical transmission systems, electrical

machines and variable speed drives; high power electronic converters and high voltage engineering. This requires engineering on a grand scale, such such as power distribution across Southern Africa. Power generation from renewable resources, such as wind and sun, and electrical transport, such as battery electrical vehicles, are of growing importance in the electrical engineering field and postgraduate postgr aduate studies. Electronics - the study of components and circuits used to construct items such as audio amplifiers,

radio transmitters and computer circuits. Students learn about elementary electrical components, transistors, integrated circuits, computer circuitry circ uitry and power electronics. The field specialises in areas such as microwave electronics, superconducting electronics, ultra-high speed electronics and the prevention of electromagnetic interference between devices. Electromagnetic systems - are diverse and complex, ranging from the study of the electromagnetic

effects of motors and electrical insulators to radio and radar antennas, radio waves and visible light (fibre optics). The scope of study ranges from undergraduate introductory courses to world class research at graduate level. Computer systems - students are trained to design and implement computers and digital electronic

systems. This field also covers the design and construction of microcomputers microcomputers built to control almost every electrical appliance, from automatic irrigation irrigation systems to autopilots autopilots for aircraft. Computer programming for embedded systems and reconfigurable logic circuits and the use and development of real time operating systems to address a variety of engineering problems, are also of key importance. Control systems - range from the temperature control in air conditioning systems to the sophisticated

automatic landing systems that allow aircraft to land autonomously in thick fog or to point camera systems accurately from satellites to target areas areas on the ground. Students learn techniques to des design ign control systems for both electronic (analogue) and computer (digital) implementations and also to apply the knowledge in other branches of o f engineering. Signal processing - Speech, radio waves and television images are all examples of signals. Students

study the behaviour of these signals and apply computers usefully to process them (eg speech, speaker and image recognition, software defined defined radios and prot protocols). ocols). Mathematical aids are created to analyze and understand these signals. Postgraduate students are involved with leading edge research in speech processing, radar and sonar, image processing, software defined radios and protocols/networks.
