Mastering the Invisible Force: A Deep Dive into EMI/EMC and Signal Integrity
In today's hyper-connected world, where electronic devices are packed into increasingly smaller spaces, a silent battle rages. This battle is against electromagnetic interference (EMI), the unwanted noise that can disrupt device operation, and for electromagnetic compatibility (EMC), the peaceful coexistence of all electronic systems. Simultaneously, ensuring signal integrity—the quality of an electrical signal—is paramount for high-speed digital and RF circuits. Understanding these concepts is no longer a niche skill but a fundamental requirement for any electronics engineer.

Course Overview: Building Robust Electronic Systems
This 12-week course, designed for undergraduate and postgraduate students, is a comprehensive journey from fundamental principles to advanced system design. It moves beyond abstract theory, focusing on engineering models and elegant analytical techniques used in modern electronics industries.
The course begins by constructing a simplified "EMC model" to demystify core concepts. It then systematically explores the entire landscape of EMC:
- Foundations: EMC requirements, units, and signal spectral analysis.
- Transmission & Radiation: Modeling of transmission lines and elemental radiators.
- EMI Phenomena: In-depth study of radiated/conducted emissions and susceptibility.
- Mitigation Techniques: Strategies to combat crosstalk, implement shielding, and handle electrostatic discharge (ESD).
- System-Level Design: Culminating in the holistic design of electronics for EM compatibility.
