Noise Reduction Techniques in Electronic Systems, 2nd Edition
This updated and expanded version of the very successful first edition offers new chapters on controlling the emission from electronic systems, especially digital systems, and on low-cost techniques for providing electromagnetic compatibility (EMC) for consumer products sold in a competitive market. There is also a new chapter on the susceptibility of electronic systems to electrostatic discharge. There is more material on FCC regulations, digital circuit noise and layout, and digital circuit radiation. Virtually all the material in the first edition has been retained. Contains a new appendix on FCC EMC test procedures.
Why Read This Book
You will learn time-proven, practical methods to diagnose and fix noise, EMI and ESD problems that plague real-world electronic products. This expanded second edition adds focused techniques for controlling digital-circuit emissions and low-cost EMC fixes for competitive consumer products, plus updated coverage of FCC test procedures.
Who Will Benefit
Embedded and hardware engineers, firmware developers, and product designers seeking hands-on guidance to reduce noise, meet EMC/ESD requirements, and avoid costly redesigns.
Level: Advanced — Prerequisites: Solid foundation in circuit theory and digital electronics, basic PCB layout familiarity, and experience using bench instrumentation (oscilloscope, spectrum analyzer); practical hardware debugging experience is strongly recommended.

How It Compares
More hands-on and layout-focused than Clayton R. Paul's 'Introduction to Electromagnetic Compatibility' (which is more theoretical), and more detailed on practical product fixes than Tim Williams' 'EMC for Product Designers'.
