A fresh look at electronics in the real world of Electromagnetic interference, the physical environment, and utility power . . . Despite the many advances in electronics, the semiconductor revolution, and technologies that perform well above 100 MHz--problems of noise and interference remain. One reason is the inability of circuit theory to address a number of real-world issues--utility power, grounding, the character of buildings, the nature of long cables, or questions of radiation vis-a-vis equipment. Solving Interference Problems in Electronics tackles all these areas with an amazingly accessible and down-to-earth approach that bridges the gap between the practical world and today's electronics. Highly original and pragmatic, the book uses elementary principles of physics to shed new light on EMI, and shows students and engineering professionals how to solve problems that are often beyond the scope of circuit theory. Drawing on his 30 years experience in the field, author Ralph Morrison: * Defines EMI broadly to accommodate utility power and the physical environment. * Puts questions of grounding and shielding in a completely new light. * Uses very simple mathematics that make it easy to understand what is happening and why. * Shows how interference is generated and how it impacts design. * Describes instrumentation design and specifications, including the nature of feedback and commonly encountered problems. * Provides methods and techniques for testing and evaluating designs. * Deals with questions of radiation and its correlation to equipment. * Covers interference questions in computer manufacturing and systems design. * Provides many illustrations that clarify difficult material and explain complex processes.

A practical new approach that brings together circuit theory and field theory for the practicing engineerTo put it frankly, the traditional education of most engineers and scientists leaves them often unprepared to handle many of the practical problems they encounter. The Fields of Electronics: Understanding Electronics Using Basic Physics offers a highly original correction to this state of affairs.Most engineers learn circuit theory and field theory separately. Electromagnetic field theory is an important part of basic physics, but because it is a very mathematical subject, the connection to everyday problems is not emphasized. Circuit theory, on the other hand, is by its nature very practical. However, circuit theory cannot describe the nature of a facility, the interconnection of many pieces of hardware, or the power grid that interfaces each piece of hardware.The Fields of Electronics offers a unique approach that brings the physics and the circuit theory together into a seamless whole for today's practicing engineers. With a clear focus on the real-world problems confronting the practitioner in the field, the book thoroughly details the principles that apply to:* Capacitors, inductors, resistors, and transformers* Utility power and circuit concepts* Grounding and shielding* Radiation* Analog and digital signals* Facilities and sitesWritten with very little mathematics, and requiring only some background in electronics, this book provides an eminently useful new way to understand the subject of electronics that will simplify the work of every novice, experienced engineer, and scientist.

Examines how to ground and shield electronic equipment and facilities to control interference. Explains the language of power engineers and the National Electrical Code. Lays the ground rules for safety then explains how to attack and solve problems in grounding and shielding via a field theoretic approach rather than a circuit approach. Provides background theory and describes various hardware and equipment, all key areas in grounding and shielding, ESD, screened rooms and topics in field coupling.

A unique, practical approach to the design of high-speed digital circuit boardsThe demand for ever-faster digital circuit designs is beginning to render the circuit theory used by engineers ineffective. Digital Circuit Boards presents an alternative to the circuit theory approach, emphasizing energy flow rather than just signal interconnection to explain logic circuit behavior.The book shows how treating design in terms of transmission lines will ensure that the logic will function, addressing both storage and movement of electrical energy on these lines. It covers transmission lines in all forms to illustrate how trace geometry defines where the signals can travel, then goes on to examine transmission lines as energy sources, the true nature of decoupling, types of resonances, ground bounce, cross talk, and more.Providing designers with the tools they need to lay out digital circuit boards for fast logic and to get designs working the first time around, Digital Circuit Boards: Reviews in simple terms the basic physics necessary to understand fast logic design Debunks the idea that electrical conductors carry power and signals, showing that signal travels in the spaces, not the traces, of circuit boards Explains logic circuit behavior through real-time analysis involving the fields and waves that carry signal and energy Provides new information on how ground/power planes work Outlines a software program for solving energy flow in complex networks

An essential guide to modern circuit board design based on simple physics and practical applications The fundamentals taught in circuit theory were never intended to work above a few megahertz, let alone at a gigahertz. While electronics is grounded in physics, most engineers’ education in this area is too general and mathematical to be easily applied to the problem of high speed circuits. Left to their own devices, many engineers produce layouts that require expensive revisions in order to finally meet specifications.Fast Circuit Boards fills the gap in knowledge by providing clear, down-to-earth guidance on designing digital circuit boards that function at high clock rates. By making the direct connection between physics and fast circuits, this book instills the fundamental universal principles of information transfer to give engineers a solid basis for hardware design. Using simple tools, simple physics, and simple language, this invaluable resource walks through basic electrostatics, magnetics, wave mechanics, and more to bring the right technology down to the working level.Designed to be directly relevant and immediately useful to circuit board designers, this book: Properly explains the problems of fast logic and the appropriate toolsApplies basic principles of physics to the art of laying out circuit boardsSimplifies essential concepts scaled up to the gigahertz level, saving time, money, and the need for revisionsGoes beyond circuit theory to provide a deep, intuitive understanding of the mechanisms at workDemonstrates energy management’s role in board design through step function-focused transmission line techniquesEngineers and technicians seeking a more systematic approach to board design and a deeper understanding of the fundamental principles at work will find tremendous value in this highly practical, long-awaited text.
