Duration
Fundamentals of Electromagnetic Compatibility and Signal Integrity
3 days
Overview
High-speed digital electronics serves up a plethora of electromagnetic compatibility (EMC) and signal integrity (SI) issues. This course serves as a guide for engineers seeking to understand the complexities of electronic systems' harmonious coexistence. Delving into EMC principles, participants will explore the art of designing circuits and devices that can function reliably without interfering with each other or succumbing to external disturbances. From understanding signal propagation and transmission line theory to shielding techniques and grounding strategies, participants will emerge with the expertise to tackle electromagnetic challenges, ensuring optimal signal integrity and fostering seamless communication across diverse electronic platforms.
