| Chapter | Topics Covered | | :--- | :--- | | | A comprehensive introduction covering noise and interference, global EMC regulations (FCC, EU, military standards), noise coupling methods, and regulatory processes. | | 2. Cabling | A deep dive into capacitive and inductive coupling, the effect of shields on coupling, shield transfer impedance, and an analysis of coaxial cables, twisted pairs, and braided shields. | | 3. Grounding | A critical analysis of AC power distribution, safety grounds, single-point and multipoint ground systems, equipment/system grounding, and the persistent problem of ground loops. | | 4. Balancing and Filtering | Discussion of balancing techniques and common-mode rejection ratio, as well as filtering strategies and common-mode filters. | | 5. Passive Components | A practical look at the non-ideal characteristics of capacitors, inductors, transformers, resistors, ferrites, and transmission lines. | | 6. Shielding | A detailed analysis of shielding effectiveness against near and far fields, absorption/reflection loss, the impact of apertures, and the use of conductive gaskets and coatings. | | 7. Contact Protection | Essential guidance for suppressing transients from relays, switches, and inductive loads, including AC vs. DC circuits and transient suppression networks. | | 8. Intrinsic Noise Sources | Theoretical and practical analysis of internal noise sources, such as thermal (Johnson) noise and shot noise, which are inherent to components. | | 9. Active Device Noise | An examination of noise generated within active devices like transistors and integrated circuits. | | 10. Digital Circuit Grounding | Focuses on the unique grounding challenges of digital circuits, including ground plane impedance and digital logic current flow. | Grounding | A critical analysis of AC power

He explains how to effectively use shielding to protect circuits from radiated emissions. The Value of the "PDF" and Digital Resources and design tables

If you want to apply Henry Ott's principles to your projects today, keep these core rules in mind:

Due to its extensive use of detailed layout diagrams, cross-sectional schematics, and design tables, many practicing engineers prefer keeping a hardcover copy on their test benches for immediate, tactile reference during troubleshooting sessions.

All these devices use electrical signals to work. Sometimes, these signals can mess with each other. This problem is called electromagnetic interference, or EMI.
