Digital Design

The course is a basic introduction to the principles of digital design and the elementary digital circuits that make up a computer system. The aim of the course is to familiarize students with logic functions, the Boolean Algebra that governs them, the implementation of logic functions with gates, and an introduction to combinational logic and modern sequential circuits (flip-flops). Finally, the course aims to familiarize students with certain characteristics and useful asynchronous sequential circuits, e.g. counters, and digital design block elements, such as encoders/decoders, multiplexers/demultiplexers, adders and subtractors. Upon completing the course, the student should be able to understand how the most basic structural elements of a computer design work, so that they can then use them to design more complex computer systems.

In summary, the course content covers basic concepts, methodologies, and technologies of Digital Design. More specifically, the focus areas are:
information representation in different number systems – Boolean Algebra – logic functions and logic gates – combinational circuits – synchronous sequential circuits – asynchronous sequential circuits – adders/subtractors, counters, multiplexers/demultiplexers, encoders/decoders, random access memory.

On a weekly teaching basis, the content is organized as follows:
