Duration:1 Semester
Credits: 5
NFQ Level:Fundamental

Valid From: Semester 1 - 2020/21 ( September 2020 )
Module Delivered in 3 programme(s)
Module Coordinator: MARTIN HILL
Module Author: DAVE HAMILTON
Module Description: This module introduces the learner to the basic building blocks of modern digital electronics. Assuming no prior knowledge, it begins with the basic logic gates from which all digital and computer systems are built, dealing with simple binary numbers processed by these systems, and goes on to develop and refine more advanced circuits as the module progresses.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Convert between binary, BCD, decimal, and hexadecimal number systems and perform simple operations on numbers in these formats.
LO2 Draw logic symbols, truth tables, and Boolean expressions for all basic logic gates, use these to construct logic circuits and identify suitable SSI chips to implement these circuits.
LO3 Perform all elements of a design cycle, including using algebraic and mapping techniques, for simple combinational logic circuits from a given specification to an efficient implementation with universal NAND/NOR logic.
LO4 Work alone and in groups to construct simple logic circuits on breadboard. Measure and analyse the performance of these circuits using modern simulation software, and standard laboratory test equipment. Verify correct operation using truth tables, timing diagrams.
LO5 Write short laboratory reports, in accordance with accepted engineering professional standards.
LO6 Conduct themselves in accordance with professional engineering standards while collecting and reporting on experimental data and in their dealings with others.
Pre-requisite learning
Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
