ATI's Practical EMI Fixes course

Share |


    Technical Training Short On Site Course Quote

      This four-day course is designed for technician and engineers who need an understanding of EMI and EMI fix methodology. The course offers a basic working knowledge of the principles of the EMI measurements, EMI fix selection, and EMI fix theory. This course will provide the ability to understand and communicate with communications-electronics (C-E) engineers and project personnel relating to EMI and EMI fix trade-offs.

      Dr. William G. Duff (Bill) received a BEE degree from George Washington University in 1959, a MSEE degree from Syracuse University in 1969, and a DScEE degree from Clayton University in 1977.

      He worked for SENTEL and Atlantic Research and taught courses on electromagnetic interference (EMI) and electromagnetic compatibility (EMC). He is internationally recognized as a leader in the development of engineering technology for achieving EMC in communication and electronic systems. He has more than 40 years of experience in EMI/EMC analysis, design, test and problem solving for a wide variety of communication and electronic systems. He has extensive experience in assessing EMI at the circuit, equipment and/or the system level and applying EMI mitigation techniques to "fix" problems. Bill has written more than 40 technical papers and four books on EMC. He is a NARTE Certified EMC Engineer.

      Bill has been very active in the IEEE EMC Society. He served on the Board of Directors, is currently Chairman of the Fellow Evaluation Committee and is an Associate Editor for the Newsletter. He is a past president of the IEEE EMC Society and a past Director of the Electromagnetics and Radiation Division of IEEE.
