Technical Theme Topics

Abstract

Spread Spectrum modulation techniques have been widely used for many years in power converters and digital circuits to spread EMI emissions and comply with EMC regulations. However, many researchers are questioning the actual impact of these techniques in terms of coexistence with modern communication systems, which necessarily involve a reflection on the adequacy of the measurement methods specified by standards in the presence of these modulations. In these two articles, the authors share their experience and reflections on the subject by providing interesting food for thought for further analyses and future standardization. As a regular reader of this column, and I am sure I can speak on behalf of all readers of the EMC Magazine, I would like to take this opportunity to thank Prof. Christos Christopoulos for the unique and special impression he has given to this column, and for the outstanding work he did for years in providing us with the opportunity to approach relevant EMC topics that were often quite complex, in an easy to understand way. For me it is a big honor, and yet a challenge at the same time, to be the Associate Editor for this column following his outstanding effort. I truly hope to be able to provide the readers of the EMC Magazine with several interesting themes as Christos did for many years.
