Summary of Content

The aim of this module is to provide the student with the knowledge and skills required to understand and deal with the concepts and applications of analogue and digital communications and to analyse the behaviour of simple signals in the frequency domain. Material on transmission lines, and propagation of signals is also presented. It balances a systems approach with sufficient detail about 'real world' applications to equip the student to do useful work.

Syllabus

Special Analysis of Periodic Signals: Amplitude-and-phase-spectra concepts, Fourier series representaiton of continuous signals, power representation in the Fourier series, signal bandwidth. Analogue Modulation: Amplitude modulation, modulation index, bandwidth and power in an AM signal, DSB-AM, DSB-SC, SSB-SC, VSB, frequency modulation, bessel functions, simple modulator and demodulator circuits, the tuned-radio-frequency-receiver, the superheterodyne receiver, IF. Digitisation of Continuous Signals: Sampling, PAM, PCM, quantisation error, A-Law and m-Law compression, delta modulation. Digital Data Transmission: Transmission media, digital signalling techniques, characteristics of line codes, data rate and bandwidth, error detection, channel capacity, transmission impairmants and limitations. Data Link Control: Sliding window, ARQ techniques; Example of DLC Protocol; HDLC. Digital Modulation: ASK, FSK, PSK, 4-QAM, 16-QAM, modems. Transmission Lines: Equivalent circuits, characteristic impedence, reflection coefficient, propagation of sinusoidal and pulsed waves, VSWR, optical fibre cables. Local Area Networks: 7 layer OSI communcations model, peer-to-peer communication, data encapsulation, LAN topologies, medium access control, CSMA/CD (IEEE 802.3), binary exponential back-off, collision window, token passing bus (IEEE 802.4), ring management frames, comparison of bus LANs, token ring (IEEE 802.5), physical implementations. Network Devices: Hub, Bridge, Routers, Switches, Routing Tables.

Learning Outcomes

On completion of this module the student should be able to:-Use frequency-domain representations of signals and convert simple signals between time and frequency domains.Explain conceptually and mathematically a range of analogue and digital modulation methods.Describe and analyse pulse code modulation (PCM) systems, for digital transmission of analogue signals, with reference to parameters such as banwidth, dynamic range, quantisation noise, sampling frequency and PCM bit-rate.Describe and analyse digital line transmission systems, with reference to electrical line characteristics, channel capacity, line coding techniques, bit-rate, signal bandwidth, error detection, clock synchronisation.Describe the operation of Data link control Protocols under various data flow conditions.Explain conceptually the ISO reference model and the key mechanisms to control and manage the exchange of information in peer to peer communication.Describe and assess the topologies and methods of media access control employed in LANs.Understand the operation of network devices and construct Basic routing tables.

Teaching / Learning Strategy

Essential theory and the rigour of analysis is presented in lectures and tutorials with laboratory exercises to allow the student to explore many areas of the syllabus best presented by practical demonstration. Laboratory time and directed learning will also be used to engage the student in design studies to reinforce the essential theory and put it in the context of real world applications. Computer based analysis and simulation tools will be introduced as appropriate. Through directed learning the student will be encouraged to take advantage of good quality self-paced computer based learning through packages in the subject matter when they are available.
