Traditional swept-tuned EMI spectrum analyzers and step-tuned EMI receivers may produce misleading or entirely false measurement results when the signal under study is not steady state, but transient. See Eric Bogatin's review of a demo by Lee Hill on this subject.
TangiTek, LLC has been awarded a National Science Foundation (NSF) Small Business Innovation Research (SBIR) grant for $224K to conduct research and development (R&D) work on Novel Three Dimensional Flocked Carbon Fiber Microwave Absorbers.
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC7124, a high efficiency, 4 MHz synchronous dual output buck regulator that incorporates a constant frequency, peak current mode architecture.
Reducing electromagnetic interference (EMI) is a key challenge when designing electronic devices. In this article, we will take a look into EMI challenges, the role of board-level shields (BLS) in reducing EMI, and the key criteria to keep in mind when selecting BLS.
Levent Sevgi, who has worked with electromagnetics for almost three decades, wrote this book to address the breadth of EMC engineering topics that are not covered by more specialized texts: market control, accreditation, calibration, EMC testing and measurement and mitigation.
Get a basic EM understanding of resonant behavior, a method for quickly determining resonant frequencies, and a secondary set of metrics to evaluate if a frequency is excited or not.
