EEEN2003J Digital Electronics

Academic Year 2021/2022

Digital electronic circuitry forms the heart of virtually all complex electronic and computer systems. This is an introductory course in the field of digital electronics. It starts with the basic logic operations and the logic elements that can perform those operations, and works towards the design of more complex digital systems.

Topics include:
- Binary systems: logic gates, Boolean algebra, number formats;
- Combinational circuits: simplification of combinational expressions, arithmetic circuits, control circuits, multiplexers and decoders;
- Sequential circuits: flip flops, registers, counters, synchronous state machines;
- Implementation technologies and performance metrics: CMOS logic, timing considerations

The laboratory component of the course provides an opportunity to simulate, build and test some digital systems. Simple circuits will be built using integrated circuits on plug-in circuit boards.

Learning Outcomes:

On successful completion of this module, students should be able to:
- Use and explain the different ways of representing unsigned and signed rational numbers e.g. decimal, binary (unsigned, sign and magnitude, one's complement and two's complement), and hexadecimal; the advantages and disadvantages of each of these number systems, and how to convert numbers between them.
- Write Boolean algebraic functions that describe a given system or circuit, and simplify this system using Truth Tables and Karnaugh maps.
- Perform binary arithmetic, and explain the digital circuits that perform these arithmetic operations.
- Analyse the operation of synchronous and asynchronous digital circuits and subsystems, using state equations, state diagrams, and transition tables.
- Design a synchronous digital circuit to meet a given specification.
- Have a basic understanding of the factors that limit the performance of digital systems e.g. timing issues, etc...
