The aim of this project is to develop methods of characterising the immunity of components and predicting the immunity of electronic systems to electromagnetic interference. Current methods of measuring component immunity provide limited information on how the component will perform as part of a system. The problem of predicting system immunity to electromagnetic interference presents a significant challenge without accurate characterisation of components (e.g. integrated circuits). However using statistical and approximate methods it may be possible to predict the likelihood of system failure in a way that allows the designer to spot weaknesses and compare alternate designs. The project will involve the development of statistical models and measurements to determine component and system immunity to validate those models.
