This is the first of two articles devoted to an eye diagram. In this article, the fundamental definitions and concepts are presented.

This month’s column is the last of three parts devoted to designing, testing, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

Bias tees are an important tool for many applications including vector network analysis. As accurate understanding and modeling of power electronic components becomes increasingly important for the study of their electromagnetic emissions, so do broadband measurements with bias tees. This paper describes the composition of such a special bias tee in terms of the necessary geometries and circuitry.

Search and rescue transmitter interferes with car alarms, central locking, and garage door openers in Las Vegas.

The U.S. Food and Drug Administration (FDA) has finalized its guidance on electromagnetic compatibility...

This is the second of three articles devoted to the design, test, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

Walkie-talkies interfere with electronic door locks on aircraft cockpits.

This is the first of three articles devoted to the design, test, and electromagnetic compatibility (EMC) immunity evaluation of multilayer PCBs containing analog circuitry. In this study, there are seven design variants that all contain a similar schematic but implement different PCB layout techniques.

Navigation and control instruments can be caused to malfunction. During the approach of an Alitalia aircraft at Turin airport on 31 December, 1995, one of the 160 passengers onboard switched on his mobile phone, thus blocking the plane’s autopilot system.

This article presents a simple method of estimating the parasitics of the three passive circuit components (R, L, C).
