In this module, the fundamentals of electronic and electrical engineering are covered. It will begin with analogue circuits describing the fundamentals of circuit analysis and the design of analogue devices. The fundamentals of digital systems will then be covered using Boolean algebra and related techniques to analyse digital circuits up to an introduction to flip flops. Finally Electrical power and machinery systems will be introduced.

Main assessment: (30%) ongoing Canvas based combined formative/summative assessment e.g. quizzes with feedback opportunity to consolidate learning every week (already set up)
(20%) laboratory data submission collected weekly
(50%) end of module assessment: Multiple choice timed examination taken remotely or at invigilated PC clusters on campus, questions will appear in random order and are drawn from question banks.
Supplementary/Reassessment Multiple choice timed examination taken remotely or at invigilated PC clusters on campus, questions will appear in random order and are drawn from question banks. Questions will cover topics and skills explored in lab so all learning outcomes are covered.
