The month's Banana Skins covers various electromagnetic interference issues in different contexts. It discusses problems with video projectors affecting audio induction loops, switch-mode power supply emissions varying with voltage, hybrid vehicle EM emissions, computer interference with amateur radio, electrostatic discharge in fluid lines, and communication equipment in ambulances causing radio interference.

We are proud to carry on the tradition of sharing Banana Skins for the purpose of promoting education for EMI/EMC engineers.

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.

Many manufacturers believe that third-party testing is required to meet the requirements of the EU’s EMC Directive. But there are other, legally acceptable paths to demonstrate compliance with the EMC Directive that do not require the use of a third party.

The paper machine process requires precise control of the paper sheet tension as it progresses through the machine.

One car manufacturer found that the craze for CB radio caused more than a jamming of the airwaves.

Spacecraft now and of the future are being controlled by EMC requirements of the past.
