Pre-Requisite Knowledge

Circuit Theory and Analysis

Summary of Content

This course will provide the student with an awareness of the scope of digital electronics and the components, methods and strategies used in the design and application of digital circuits.

Syllabus

The teaching syllabus will cover the following areas: Logic Devices: The operation of AND, OR, NAND, NOR gates, adders, encoders, decoders, registers, buffers, multiplexers/de-multiplexers, Read-Only memory, static and dynamic Random Access memories; Semiconductor types - TTL, ECL, MOS and CMOS; densities - SSI, MSI, LSI and VLSI; output drives - Open Collector and Tri-State implementations. Combinational Logic: The analysis and comparison of combinational, asynchronous and synchronous systems in terms of function and timing. The design of combinational, asynchronous and synchronous systems such as Counters and Sequencers, using state tables and state diagrams in basic digital components. The implementation of such circuits - use of appropriate sources of information; to choose components suitable for the particular application; produce PCB masks by physical methods and production of PCB masks by Electronic Computer Aided Design. Programmable Logic Devices: ROM, PLA, PAL, critical evaluation, use of these in the implementation of circuits. A/D and D/A Conversion: The concepts of representing analogue signals in a digital format. Discussion of typical circuits which can implement A/D and D/A conversion, interface methods, typical examples of application.

Learning Outcomes

On completion of this module the student should be able to:1. Define the meaning of the terms TTL, ECL, MOS, CMOS, Tri-State, SSI, MSI, LSI, VLSI, ECADCAD, PLD, ROM, PAL, PLA, DAC, ADC. (AM1)2. Describe the operation of basic digital components such as logic elements, adders, encoders/decoders, registers, buffers, multiplexers, de-multiplexers and memories.(AM1, AM5)3. Design combinational and sequential circuits for given specifications. (AM1, AM5)4. Evaluate various types of PLDs for their use in the implementation of typical combinational and sequential circuits. (AM1)5. Examine the methods of interfacing digital circuits to analogue circuits, including DACs and ADCs.(AM1,AM5)

Teaching / Learning Strategy

The main teaching method will be based on lectures. The students will be expected to perform directed reading exercises and self-learning exercises on emerging technologies. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.
