Application Note Overview

As electronic systems become smaller, faster, and more densely integrated, maintaining reliable performance in increasingly noisy electromagnetic environments becomes more challenging. Unwanted electromagnetic interference (EMI) can affect system operation, delay compliance, and lead to costly redesigns if it is not addressed early in the development process.

This application note explains the fundamentals behind electromagnetic compatibility (EMC) and shows how a stronger understanding of electromagnetic behavior can help engineers make more informed design and testing decisions. By considering EMC earlier in development, teams can reduce the risk of unexpected issues during compliance testing and improve the likelihood of meeting compliance requirements without unnecessary redesign.
