Grounding and shielding. I. Noise

Noise affects most devices. Designing adequate shielding does not have to be a black art-in fact, it should not be. Some basic understanding and the application of appropriate principles will eliminate most problems. This article is the first of a four-part series that covers the basics of noise, grounding, and shielding. This article describes various mechanisms of noise-understanding them will give immediate insight into avoiding noise problems.
