Introduction If your job involves electronics design, system development, electromagnetic interference (EMI) testing and troubleshooting, you might encounter the terms "noisy ground" and "clean ground." Technically, there is no such thing as "noisy or clean ground." However, these terms are commonly used in the engineering world despite their inaccuracies. They often give engineers the impression that the earth/ground is an infinite sink of electrical noise, disregarding the

A step-by-step guide to excellent engineering practice Bench-top EMC pre-compliance testing is often carried out under time pressure, yet the quality of the test report directly determines how effective troubleshooting will be Before committing to writing this article, I had two main thoughts: First, I’ve seen far too many subpar test reports from engineers. They often do excellent work but aren’t given enough time to document it properly. As a result, when teams sit down to
