IEEE Guidelines

Definition

IEEE Guidelines refer to the standards and recommendations established by the Institute of Electrical and Electronics Engineers (IEEE) for ensuring electromagnetic compatibility (EMC) and mitigating electromagnetic interference (EMI) in electronic systems, particularly in printed circuit boards (PCBs). These guidelines provide a framework for the design, testing, and implementation of electrical systems to minimize unwanted electromagnetic effects, thus enhancing performance and reliability.
