Summary of Content

The aim of this module is to provide the student with the knowledge and skills required to understand the operation of analogue and digital communication systems and to perform practical tasks on such systems.


The teaching syllabus will cover the following areas: Analysis of Periodic Signals: Amplitude-and-phase-spectra concepts, Fourier series representation of continuous signals, signal bandwidth. Introduction to noise and the effects of noise on communications systems signal to noise ratio, noise figure and cascaded amplifiers. Amplitude modulation, modulation index, bandwidth and power in an AM signal, DSB-AM, DSB-SC, SSBSC, VSB. SSB generation. Frequency modulation, Bessel functions, bandwidth and power in an FM signal. Simple modulator and demodulator circuits - AM and FM transmitters and receivers, tuned radio-frequency and super heterodyne receivers, Signals and noise: Eb/No-Receiver structure, demodulation and detection -Correlation receiver and matched filter- ISI in band limited channels. Pulse modulation: channel capacity, sampling rate/aliasing, PCM, quantizing error, TDM, b5-law compressor. Digital Modulation techniques and modems: FSK/PSK,QPSK, MSK, QAM. Pass band Transmission model- Generation, Detection, Signal space diagram, bit error probability and Power spectra of BPSK, QPSK, FSK and MSK schemes- modems, cable modems, ADSL. Data Transmission: synchronous/asynchronous. transmission, Coding schemes- Source coding, Channel coding and line coding

Learning Outcomes

On completion of this module the student should be able to: 1. Represent signals in time and frequency domains with the help of mathematical equations (AM1) 2. Explain the concept of noise and its influence in communication systems (AM1) 3. Discuss the theory and applications of analog modulation techniques (AM1,AM3, AM5)4. Illustrate the structure of transmitters and receivers used for analogue communication (AM3, AM5)5. Apply theory of digital and pulse modulation techniques for the implementation of Digital transmission (AM1) 6. Examine various coding techniques used in data transmission (AM1)

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 topics related to Electronic communications. Tutorials will be used to reinforce the module material and to discuss the issues raised by the directed reading.
