Firmware is integral to the operation of most devices, and may represent an easier and less expensive pathway for addressing EMC issues. This article presents different approaches to modifying firmware as well as case studies illustrating the potential effectiveness of this approach.

Numbers 291 - 294 are taken from the Appendix to MIL-STD-464A dated 18 March...

This article discusses the basics of a step-down (buck) DC Switched-Mode Power Supply (SMPS). It should serve at an entry-level tutorial and a building step towards the more advanced designs.

The regular “Banana Skins” column was published in the EMC Journal, starting in January 1998.

If you’re an electrical engineer and consider proper EMC shielding a mechanical only issue, please reconsider your position and keep reading. Proper EMC shielding is both an electrical and mechanical design issue. Thoughtful coordination between the two disciplines is key to successful EMC shielding implementation on most product development projects.

Are you just getting into software simulation and feeling a little overwhelmed with all the new jargon? This brief article will explain some of the most common terms used in the very exciting world of EMC/Signal Integrity simulation software, all in one location.

Answering the needs of managing EMI in actual use, this article provides hands-on guidance to specialists at the factories and elsewhere on measuring conducted EMI where it matters – in their environment. Anyone who knows how to use an oscilloscope can perform such measurements.

Wireless devices are now in the legislative spotlight the world over. Safety, performance, spectrum usage and protection of personal data are all matters of regulation, although countries vary in how they regulate such concerns. This article looks at Australia as a case study, reviewing the overarching legal framework, the role of the national regulator, conformity assessment and the use of standards.

The Banana Skin columns were compiled by Keith Armstrong, of Cherry Clough Consultants Ltd, from items he found in various publications, and anecdotes and links sent in by the many fans of the column.

This article discusses the origins, justification, and interrelations between some of basic EMC rules regarding the highest significant frequency (bandwidth) present in digital signals, definition of the electrically short structures, and the transmission line criterion.
