This webinar introduces the fundamentals of electromagnetic compatibility (EMC) and explains how it can be applied in practical electronic designs. It starts by clarifying what EMC means and why it is essential for ensuring that electronic systems operate reliably without causing or suffering from interference. A key focus is on understanding how electromagnetic interference arises and how design decisions influence system behavior. The session uses simple analogies to make complex EMC concepts easier to grasp and connects them to real-world engineering challenges. The webinar also emphasizes the importance of PCB layout, showing how routing, grounding, and component placement affect electromagnetic performance. Additionally, it highlights the role of electromechanical components - such as connectors and shielding solutions - in improving EMC and reducing unwanted emissions. Overall, it provides a practical introduction to EMC principles, helping engineers design more robust, compliant, and interference-resistant electronic systems.
