This page is provided to assist lecturers and students in the other Caribbean islands - so that they may keep pace with us as we explore the world of Digital Electronics ! Tutorials and Answer Sheets will be available as we progress Course Outline: ----------------------- Lecture 1 - Rules of Boolean Algebra, AND - OR - NOT gates, truth tables Lecture 2 - Additional boolean identities, NAND - NOR - XOR - Exclusive-NOR gates Lecture 3 - Applications and examples of digital logic systems, input and output Consensus Theorem and examples of reduction of expressions to simplest form Lecture 4 - Canonical and standard forms, Sum of Products (SOP) and Product of Sums (POS), minterms and maxterms Lecture 5 - Karnaugh mapping of 2,3,4-variable functions (with example of minimisation using this method), conversion between SOP and POS form.
