Analog and Digital Communications
|Course code ELEC3540||Units 10||Level 3000||Faculty of Engineering and Built EnvironmentSchool of Electrical Engineering and Computer Science|
This course provides a thorough introduction to the basic principles and techniques used in analog and digital communications. The course will introduce analog and digital modulation techniques, communication receiver and transmitter design, baseband and bandpass communication techniques, line coding techniques, noise analysis and multiplexing techniques. The course also introduces analytical techniques to evaluate the performance of communication systems.

|Objectives||This course provides students with a very good understanding of basic communication engineering techniques and principles related to transmission of information over wired and wireless communication channels. The course starts with a review of the Fourier transform and information signal properties. The course then focuses on developing an understanding of the principles and techniques of analogue modulation. Communication transmitter and receiver design techniques are discussed for different transmission conditions. Noise analysis techniques are also introduced. The course then covers a range of digital modulation techniques which are frequently used in modern communication systems. The course also introduces a range of baseband and bandpass communication techniques including different line coding techniques. Optimal digital receiver design techniques are briefly discussed. Multiplexing techniques are also discussed in the course. After completing the course students will develop good understanding of basic communication techniques and have the ability to analyse the performance of communication systems.|
