Dr. Bogdan Adamczyk is professor and director of the EMC Center at Grand Valley State University (http://www.gvsu.edu/emccenter/) where he regularly teaches EMC certificate courses for industry. He is an iNARTE certified EMC Master Design Engineer. Prof. Adamczyk is the author of the textbook “Foundations of Electromagnetic Compatibility with Practical Applications” (Wiley, 2017) and the upcoming textbook “Principles of Electromagnetic Compatibility with Laboratory Exercises” (Wiley 2022).
This article uses a classical circuit-theory model of a series RLC circuit to explain the phenomenon of ringing on a transmission line, or a PCB trace.
This s-parameters tutorial consists of two parts: Part I discusses the fundamental background needed to understand the concept of s-parameters; Part II explains the s-parameters use in EMC measurements and testing
This article is devoted to the radiated emissions measurements. These measurements can be performed either at the Open Area Test Site (OATS) or in an Absorber-Lined Shielded Enclosure (ALSE).
Foundations
Consider the transmission line circuit shown in Figure 1. A sinusoidal voltage source with its source impedance drives a lossless transmission line with characteristic impedance ZC, terminated in... Read More...
