Aims: To introduce students to the principles of signals, systems and communications.
At the end of this unit students will be able to:
(i) distinguish between different types of generic signals, construct mathematical models of signals and systems and apply these models to predict the response of a linear system to a specified stimulus, and
(ii) explain the functions of the principal components of a communications system, describe the information content of natural languages and the origin (and technological role) of redundancy.
Application of the information, techniques and methods discussed in the lectures to solving engineering problems in signals, systems and communications. Taught, facilitated and tested.
* Signals and Systems Theory - Signals: review of signal types, phasors, Fourier series. Linear systems: impulse response, convolution, requency response, convolution theorem.
* Communication Systems - Introduction to modern telecommunications networks, services, and signals. Information theory and source coding. Communication channels and noise.
