Applying Practical EMI Design and Troubleshooting Techniques
Sign up for course news to hear about future course dates.
This course gives engineering professionals the ability to successfully recognize, solve and avoid challenging EMI problems.
Demonstrations using working hardware illustrate concepts such as radiated emissions, high frequency antennas, radiated and conducted immunity and crosstalk in connectors, cables and IC packages.
This course is appropriate for experienced circuit and system design engineers, EMC engineers, as well as those who are new to EMI problem solving.
The course is based on over 30 years of hands-on troubleshooting experience and the latest EMC research.
