This course gives an introduction to the basic theory, construction,
design, operation and use of electrical machines and how electrical machines
fit into the larger context of power systems. Emphasis is put on understanding
the basic concepts of electromagnetic laws governing the working of electrical
machines including motors, generators and transformers. Practical analytical
models for most types of electrical machines commonly used in industry will be
developed, and the models will be used to analyse power requirements, power
capability, efficiency, operating characteristics, control requirements, and
electrical demands of these machines
A. Course Introduction
Digital Electronics is a field of electronics that involves the study of digital signals and the engineering of
devices that use or produce them. In contrast to analog electronics, where information is represented by a
continuously varying voltage, digital signals are represented by two discrete voltages or logic levels.
B. Course Content
Digital Electronics covers combinational and sequential logic circuits. Topics include number systems,
Boolean algebra, Logic gates and families, Logic circuits, Minimisation of logic circuits, Sequential logic
systems, Latches, flip-flops, Counters, shift registers, Memories, Medium Scale Integration (MSI) and
Large-Scale Integration (LSI) circuits, Analogue to Digital (AD) and Digital to Analogue (DA)
conversion.
C. Course Objectives
The objectives of this course are to:
i. Acquire basic knowledge of digital logic levels;
ii. Understand digital electronics circuits; and
iii. Prepare students to analyse and design various digital electronic circuits.
D. Course Outcomes
At the end of the course students will:
i. Have a thorough understanding of the fundamental concepts and techniques used in digital
electronics;
ii. Understand and apply various number systems in digital design;
iii. Acquire the skills to analyze and design various combinational and sequential circuits; and
iv. Develop their skills in building and troubleshooting digital circuits.
E. Mode of Course Delivery
Lectures (face-to-face and online using Virtual Learning Environment), tutorials, oral conversation.
