This Application Note describes the various methods and combinations of methods for grounding and shielding. Following these recommendations will help minimize or eliminate problems encounters with electrical noise in your application. For more information, see EMI Checklist .

EMI (Electro-Magnetic Interference) comes in different forms, frequencies, and levels. Electronic equipment has different categories for both emissions and susceptibility. Under normal circumstances elimination is not possible so reduction to acceptable levels is what can be reasonably achieved. Coupling factors, rise time, emissions and susceptibility are phrases that must be understood with confidence. It is less “Black Art” than the urban legends lead you to believe. It’s well founded in principal and practice.
