The purpose of this unit is to provide an introduction to the specialised techniques and components which are common to both analog and digital communication systems. Topics studied include phase locked loops, noise, modulation methods, electromagnetic propagation, antennas and optical fibre communication. The relevance of these topics is illustrated by reference to existing communication systems such as the telephone network, TV, cellular mobile and microwave radio, radar, radio navigation aids, and satellite communication systems. The unit is intended for final year electrical degree students, and assumes a knowledge of electromagnetic fields and Maxwell's equations.
