Description:

This expanded third edition of the most popular book on electromagnetic compatibility reflects all of the latest advances and developments in the field. It demonstrates how and why noise in electronic digital systems can be avoided or minimized. Although much will be added (including five new chapters) and updated in this edition, virtually everything that was in the second edition is still applicable and will remain in the third edition. This book is essential for design engineers in the electronics industry and students in EMC.
