Interference in electronic equipment is a constant source of difficulty for the design and systems engineer. The common practice is to follow some established rules that may not always work. There is no coherent theory that engineers can refer to in their design work, and the solution of interference problems is therefore often considered to be an art. This book bridges the gap between the practical world and today's electronics. It treats interference problems from a physics perspective, covering radiation, utility power and safety, the nature of long cables, and other factors that must be considered for modern electronics. Readers will understand grounding and shielding in a new light.
