Learning Outcomes

On completion of this module the student should be able to:1. Describe the features of telephony systems for modern communication systems (AM1, AM7,AM8)2. Explain the role of television transmissions at VHF and UHF for various service provisions (AM1, AM7, AM8).3. Discuss the characteristics and properties of radio waves and modes of radio wave propagation suitable for terrestrial TV and satellite applications (AM1, AM7, AM8).4. Analyse the essential characteristics of transmission lines and their applications (AM1, AM7,AM8)5. Analyse digitising, coding, data compression, multiplexing and scrambling necessitated by the advent of digitisation of TV signals (AM1, AM7,AM8).6. Analyse and evaluate performance characteristics and applications of satellite systems (AM1, AM7, AM8).7. Design antennas through understanding of antenna radiation fundamentals and antenna characteristics for various applications (AM1,AM5,AM7)

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 and to discuss the issues raised by the directedreading.
