This subject has the following teaching availabilities in 2009:

431-328 Digital Systems 3: Circuits and Systems

For the purposes of considering request for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005), and Student Support and Engagement Policy, academic requirements for this subject are articulated in the Subject Overview, Learning Outcomes, Assessment and Generic Skills sections of this entry.

It is University policy to take all reasonable steps to minimise the impact of disability upon academic study, and reasonable adjustments will be made to enhance a student's participation in the University's programs. Students who feel their disability may impact on meeting the requirements of this subject are encouraged to discuss this matter with a Faculty Student Adviser and Student Equity and Disability Support: http://services.unimelb.edu.au/disability

On completion of this subject, students should have an understanding of some advanced topics in digital system design, taken from the following.

Timing in digital systems - clock distribution, including sources and management of skew; metastability and synchronisation; the effect of loading; synchronous and asynchronous bit level transport, including line coding, scrambling, clock recovery, timing requirements, jitter (sources and effect), jitter filtering and bit stuffing.

Noise in digital systems - signal referencing; grounding; crosstalk; simultaneous switching; power supply distributions and related issues including impedance of parallel planes, loss and damping, impedance control over frequency, decoupling and interaction of lumped and distributed impedances.

Interfacing to the analogue world - sample and hold circuits; techniques for converting between analogue and digital representations of signal; noise analysis and quantisation effects.

On completion of this subject the student should be able to:

1. Explain, assess and apply timing analysis and design techniques to the end of achieving reliable and repeatable operation of digital systems in the face of the limitations imposed by realisation technologies;

2. Explain, assess and apply techniques for managing sources of noise in electronic realisations of digital systems;

3. Model and assess the performance of techniques for digital sampling of analogue signals.

One 3-hour end-of-semester written examination (70%); mid-semester test and/or project report not exceeding 20 pages including appendices, diagrams, tables, graphs and computer output (30%). The relative weighting of test and/or project report will be specified both in the first lecture and on the subject web page at the start of semester.
