To provide a detailed knowledge base for the functions and operation of the principal elements of digital communication systems and their application in the mobile and personal communications arena.

Learning Teaching & Assessment Strategy:
Concepts, principles & theories explored in formal lectures, practiced in tutorials and demonstrated in laboratory classes.
Practical skills developed in laboratory sessions and worked examples and tutorial sessions.
Oral feedback is given during labs and seminars. Two design case studies (50%) will assess your grasp of the knowledge base of the module; and a formal examination (50%) will assess the learning outcomes expressed in the descriptor.
Supplementary assessment - repair deficiencies.
