Bandwidth

A more thorough “in-between calibration cycle” check of the ESD simulator’s output waveform is something every EMC engineer and technician should consider.

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.

In this first part of a two-part article, we’ll discuss the use of radio modules to enable wireless connectivity of electronic and consumer products, and how to approach radio, EMC and safety regulatory approvals in North America for radio modules and equipment which contain radio modules.

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.
