ELEC94011 Introduction to Signals and CommunicationsLecturer(s): Prof Kin Leung Aims
To introduce principles of communication systems and methods used in modulating and demodulating signals in order to carry information from a source to a destination.
Learning Outcomes
For each major topic the objectives are similar:
To identify how to use Fourier series and Fourier transforms in communication systems to achieve distortionless transmission. To indicate why we need the modulation To introduce mathematical models involved in modulation and demodulation processes To describe how signals can be transmitted using amplitude, frequency and phase modulation schemes and demodulated to receive the transmitted signals. To learn how digital transmission schemes can be used for communication systems. Syllabus
This course will have about 20 lectures. Each section will have an associated set of printed notes with attached problems; the notes and lectures are intended to complement each other, and so neither should be taken as sufficient on its own. Problems will be discussed in study groups.
