Prerequisite Modules:

Rationale and Purpose of the Module:

This module is the first module in the core Digital Systems stream of the BE programmes in the department of Electronic and Computer Engineering.

Syllabus:

Introduction to digital systems Distinguish between analog and digital representations. Number systems and codes Conversion between number systems. Describing Logic Circuits Truth tables and Basic Boolean manipulation Simple Gating functions, Data selectors. Demultiplexers. Karnaugh Mapping Logic Characteristics Delays and spurious responses. Buffers, Schmidt inputs. Characteristics of CMOS digital ICs. Basic Arithmetic Unsigned numbers, signed numbers. 1's and 2's complement arithmetic Ripple carry adders Latches and flip-flops D-type level triggered. Edge-triggered D-type. J-K Timing waveforms for flip-flops Shift register operation Edge-triggering concepts,Propagation delay, set-up, hold, asynchronous inputs Registers and counters:

Learning Outcomes:

Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)

Construct a truth table for any function with up to 4 variables and write a corresponding Boolean expression Simplify a Boolean expression with up to 4 variables into a standard sum-of-products form. Convert decimal numbers into binary, hex and BCD format and vice-versa Perform addition and subtraction using 1s and 2s complement fixed point binary notation. Draw the output of a multi-level gating circuit, allowing for gate delays Draw output waveforms for D type latches and flip-flops and J-K flip-flops given the input waveforms Draw circuits based on flip-flops for simple sequential circuits based on counters and shift registers Document combinatorial circuits to a given specification Design and test a range of circuits with switches, LEDs and 7-segment displays and document results

Affective (Attitudes and Values)

N/A

Psychomotor (Physical Skills)

Build a range of circuits with switches, LEDs and 7-segment displays

How the Module will be Taught and what will be the Learning Experiences of the Students:

The module has 2 teaching hours per week, with one laboratory session of 2 hours per week. Students perform laboratory work to reinforce the lecture material, and to show the practical application of the lecture material. The assessment is typically 70% end-of-term exam, 25% laboratory work, and 5% class test
