Signals and Systems

The aim of this subject is twofold: firstly, to develop an understanding of the fundamental tools and concepts used in the analysis of signals and the analysis and design of linear time-invariant systems path in continuous–time and discrete-time; secondly, to develop an understanding of their application in a broad range of areas, including electrical networks, telecommunications, signal-processing and automatic control. The subject formally introduces the fundamental mathematical techniques that underpin the analysis and design of electrical networks, telecommunication systems, signal-processing systems and automatic control systems. Such systems lie at the heart of the electrical engineering technologies that underpin modern society. This subject is one of four Level 3 subjects that define the Electrical Engineering Systems Major in the Bachelor of Science. . It provides the foundation for various subsequent subjects, including ELEN90057 Communication Systems, ELEN90058 Signal Processing and ELEN90055 Control Systems.

• 1Apply fundamental mathematical tools to model, analyse and design signals and systems in both time-domain and frequency-domain
• 2Explain the broad applicability of the mathematics of signals and systems theory, particularly within electrical engineering
• 3Articulate the similarities and differences between the mathematical tools needed for dealing with continuous-time systems/signals versus their discrete-time counterparts
• 4Use MATLAB to study the behaviour of signals and systems as they arise in a variety of contexts.
