Produktbeschreibung

Principles of Electromagnetic Compatibility Understand both the theory and practice of electromagnetic compatibility with this groundbreaking textbook Electromagnetic compatibility (EMC), the ability of a device or system to maintain its operations in an electromagnetic environment without interference with itself or other devices, is a fundamental component of any electrical engineering design process. Understanding the basic principles of EMC is essential to undertaking even the most basic project; this understanding is attained by reinforcing the theory with laboratory exercises. Principles of Electromagnetic Compatibility is one of the first textbooks on EMC principles that includes laboratory exercises at the end of each chapter, that any engineer or student can perform with standard EMC laboratory equipment. This enables readers to connect theory to practice and combines general precepts with supporting simulations and hands-on experimentation. The result is an indispensable guide to this cornerstone of electrical engineering. Principles of Electromagnetic Compatibility readers will also find: * ALTIUM files available online which allow users to create and print their own circuit boards * Detailed treatment of subjects including Frequency Spectra, EM Coupling Mechanisms, Non-Ideal Components, Power Distribution Network, EMC Filters, Transmission Lines, Radiation, Shielding, Return Current Flow, and more Principles of Electromagnetic Compatibility is a must-own for students and practicing engineers looking for a comprehensive EMC principles guide.
