This book, which is based on material developed for a series of mathematical workshops, is aimed at first and second year students. It presents the mathematical tools they will need to use as well as a wide range of examples of electronic applications in which these tools are commonly used. Examples of the modelling, simulation and interpretation of practical electrical and electronic systems are provided using a wide range of basic mathematical techniques. There is a also a toolkit which is intended to provide a reference guide to the basic set of mathematical information needed by any electronic engineer.
