Electromagnetic Interference (EMI) is an essential consideration in modern electronic design, impacting device performance and compliance with regulatory standards. This presentation provides a brief introduction to the world of Electromagnetic Compatibility (EMC), starting with a fundamental explanation of EMI its definition, sources, and significance in electrical and electronic systems. We will explore the two primary forms of EMI radiated and conducted emissions focusing on their origins and propagation methods. The session will also outline standardized testing procedures used to evaluate emissions, highlighting key aspects designers should monitor during testing to ensure compliance. We will explain noise coupling mechanisms that influence EMI behavior, such as capacitive, inductive, and common-mode coupling. We show practical strategies for noise mitigation including grounding techniques and effective noise-filtering approaches. This presentation aims to bring awareness to engineers, designers, and technical professionals with the foundational knowledge and tools needed to identify, measure, and address EMI challenges in their designs, enabling the development of robust and compliant systems.
