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.
