A high percentage of EMI failures are related to structure resonances in a system. This hands-on article reviews work on structure resonances and their EMI impact, presents methods to identify and locate structure resonances, and suggests fixes using practical examples.
This article presents a quick and easy simulation model for filter performance analysis. The simulation model that the author built matches the test results quite well and it can serve as a useful and powerful tool for electronics design engineers.
