How to Predict and Suppress Electromagnetic Interference (Download)

Electronic equipment will typically have some immunity to electromagnetic interference (EMI). However, distortion of information from intentional or unintentional electromagnetic forces may also occur, particularly near computing equipment (CE). To mitigate EMI and ensure noise immunity, one must take action during the early stages of the development of CE.

Quite frequently, within an electromagnetic environment that’s close to CE objects that have large geometric dimensions, there may be power lines, an aircraft fuselage, a car body, metal structures in a building, lightning discharge, and more. To predict the noise immunity of CE elements, it may be possible to use physical simulation of EMI.
