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.

This course covers two key section under electrical machines. It covers
Direct Current Machines and Transformers
This course intends to provide a basic understanding of linear electronic principles and devices. It gives a balanced coverage of analogue devices and circuits, with emphasis on small and large signal amplifiers, operational amplifiers, filters, wave-shaping circuits, feedback, and stability.
Applied Electricity is a fundamental course that engineering students of almost all disciplines
have to undertake in the first semester of their programme of study. It is needless to state
that our world is heavily dependent on electricity in our day to day life. A reasonable
understanding on the basics of applied electricity is therefore important for every engineer.
Apart from learning dc and ac circuit analysis under steady-state conditions, and signal
waveforms, you will learn basic working principles and analysis of transformers, dc
machines, and induction machines.
Objective
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.
Content
Overview and application domains of AC Machinery. Induction motors, Induction generators, Synchronous generators, Synchronous motors, Special purpose machines, single phase AC machines, linear AC motors, AC tachogenerator, reluctance and hysteresis motors, switched reluctance motors, BLDC motors, AC servomotor, Stepper motors: Classification, constructional features, Principle of operation, Equivalent circuits, No-load and short circuit tests, machine characteristics, starting, speed and torque control, voltage regulation, power factor control, losses and efficiency.
