Keith Armstrong, global EMC expert at EMC Standards, a partner of the 2022 EMC and Compliance International exhibition, explains why the relevant harmonised standards are no longer sufficient for compliance with the EMC Directive and why most people must now apply IEC 61000-4-14 too.

Keith Armstrong, global EMC expert at EMC Standards, a partner of the 2022 EMC and Compliance International exhibition, explained why the relevant harmonised standards are no longer sufficient for EMC compliance and why you probably need to apply IEC 61000-4-16 too.

In this article, Keith Armstrong, FIEE/IET, Senior MIEEE, ACGI, EurIng(Gp1), on behalf of EMC Standards, outlines some of the issues he has encountered after having been asked to fix EMC problems, and how designers can learn to ensure that filtering and shielding are compatible.

Here are the results of a practical laboratory exercise for undergraduate students, taken from: 'Teaching EMC using an EMC demonstration unit', a paper submitted for the 2018 APEMC/IEEE symposium in Singapore.

During the French Revolution, beheading was the preferred method of execution. The guillotine was used for thousands of executions, meaning there was no shortage of experimental material for biologist Marie Francois Bichat. Bichat tested the electrical stimulation of hearts, which was instrumental in the development of the modern day pacemaker. Nowadays, pacemakers are commonly used to maintain a regular heart rate.
