Definition of engineering: “The creative application of scientific principles to design or develop:

• Structures,

• Machines,

• Apparatus,

• Manufacturing processes,

• Works utilizing them singly or in combination;

• Construct or operate the same with full cognizance of theirdesign;

• Forecast their behavior under specific operating conditions;

• All aspects of intended functions, economics of operation andsafety to life and property.”

Definitions – Electrical & Computer Engineering

Electrical Engineering: is an engineering field that deals withthe study and/or application of

Electricity,Electronics andElectromagnetism

Electrical engineering is considered to deal with the problemsassociated with large-scale electrical systems e.g. powertransmission, motor control, whereas electronic engineeringdeals with the study of small-scale electronic systemsincluding computers and integrated circuits.

The field first became an identifiable occupation in the late19th century after commercialization of theelectric telegraph and electrical power supply


November, 2012


Electrical Engineering now covers a range of sub-studies including those that deal with:

• Power• Control & Instrumentation

• Electronics / Microelectronics

• Signal processing• Telecommunications• Computers





November, 2012


Computer Engineering, also called Electronic and Computer Engineering, is a discipline that combines elements of both

Electrical engineering &Computer science /engineering

Computer engineers are electrical engineers that have additional training in the areas of

Software design and

Hardware-software integration

In turn, they focus less on power electronics and physics

Computer engineers are involved in many aspects of computing, from the design of individual

Microprocessors, personal computers, and supercomputers, to circuit design

Communications engineering focuses on the transmission of information across a channel such as: Coax cable, optical fibre or free space

Transmissions across free space require information to be encoded in a carrier wave in order to shift the information to a carrier frequencysuitable for transmission, this is known as modulation

Popular analog modulation techniques include amplitude modulationand frequency modulation The choice of modulation affects the cost and performance of a system

Once the transmission characteristics of a system are determined, telecommunication engineers design the transmitters and receiversneeded for such systems
