A System’s Perspective on the Use of EMI Detection and Correction Methods in Safety Critical Systems

In this paper we discuss the condition assessment definitions previously used to analyse the effectiveness of ElectroMagnetic Interference (EMI) detectors/correctors. It is shown that those definitions do not resemble the correct condition and an expansion is needed. New expanded condition assessment definitions are presented and evaluated in comparison with the old ones for a two out of three majority voter system used in an Electro Magnetic (EM) diverse system. The new definitions provide a better insight into the effectiveness of EMI detectors on its own or in correctors. We also discuss the use of the new definitions in a multi-layer error detection and correction system.
