The purpose of the module is to introduce the fundamental principles of digital and analogue electronics from system and device perspectives. Students will develop the ability to analyse and design basic digital and analogue electronic circuits and small systems. Significant elements of the learning experience will rely on problem based learning. Students are expected to participate actively in lectures, tutorials and laboratory/assignments. A kit of components is used to support this module, which must be borrowed by each student through a library loan arrangement.

Learning Outcomes

1. Explain the characteristics of basic analogue electronic circuit elements, including diodes and transistors.
2. Analyse and design basic analogue electronic circuits and systems.
3. Explain the characteristics of basic digital electronic circuit elements, including gates and flip flops.
4. Explain and solve arithmetic problems using a variety of digital number representations, including unsigned and signed binary, BCD, octal, decimal and hexidecimal.
5. Analyse and design combinatorial and sequential digital electronic circuits and systems, including adders and mixed analogue/digital circuits, through the use of DACs and ADCs with a micro-controller.
6. Build and debug digital and analog electronic circuits and systems using electronics kit, communicating with student peers, demonstrators and technical staff, and documenting experimental outcomes.
