EMC FOR PRODUCT DESIGNERS - TIM WILLIAMS

ELECTROMAGNETIC INTERFERENCE AND COMPATIBILITY (EMI / EMC)
Reference Literature Survey - Part 3
Book Review : EMC for Product Designers by Tim Williams

I have been invited to deliver a lecture on Electro Magnetic Interference and Electro Magnetic Compatibility abbreviated as EMI / EMC. I have deciced to speak on the topic of Electromagnetic Pollution (or Electropollution).

This gives me a chance to brush up my rusty knowledge and let me begin by going through a few book reviews I had written earlier when I used to regularly teach this subject at the Post Graduate Level and conduct specialized training on EMI / EMC too during my faculty days at DIAT Deemed University located in the hills of Girinagar near Pune

So, Dear Reader, in case you are interested in this topic of Electromagnetic Pollution and its manifestations, do read on:

This is Part 3 in this series.

EMC for Product Designers by Tim Williams

Book Review by VIKRAM KARVE

A Comprehensive Reference Book for Information Technology, Computer Science, Electronic, Communication and Electrical Engineering Professionals

THE BOOK

Title: EMC for Product Designers
Author: Tim Williams
Elsevier [Fourth Edition, 2007] 498 pages
ISBN – 13: 978-0-75-068170-4
ISBN – 10: 0-750-68170-5
Most of us consider a number of factors, exoteric and esoteric, while designing or selecting our homes and in the configuration of the numerous modern technological devices and domestic appliances, most of them electrical and electronic, especially in location of various rooms and in deciding where to place these appliances.

Recently I saw a programme on TV where a Vastu Shastra expert was advising viewers not only regarding the various aspects of designing and building living environments that are in harmony with the physical and metaphysical forces but also specifying optimal locations and layouts for various electrical and electronic appliances and devices in both residential homes and workplaces.

I listened with intriguing interest as he gave precise directions and specified exact locations for positioning of Televisions, Computers, Communication Devices, Microwave Ovens, Music systems and other appliances, and fascinated by the congruence between principles and aspects of Vastu and Electromagnetic Compatibility ( EMC ) and wondered whether the expert in reality was actually an EMC Design Engineer in addition to being a Vastu Shastra Specialist.

When you design or select or configure your house or office I am sure you consider various aesthetic, architectural, financial, utilitarian, geographical, interior and exterior design and other practical aspects, maybe even incorporate the principles of Vastu Shastra and Feng Shui, but do you give even a fleeting thought to EMC ... ?

In today’s world with the increasing use of electrical, communication, electronic and information technologies we are under continual exposure to Electromagnetic Field (EMF), both inside and outside our homes, in our workplaces and even in the open wherever we go, radiating from radiating from electricity power lines, household wiring, microwave ovens, computers, monitors, televisions, communication devices, cellular phones, electrical, electronic and IT appliances.

“Electro-pollution” is an increasingly serious form of Environment Pollution and merits serious consideration, as much as, if not more than, other well-known forms of pollution.

Electro-pollution seems to be omnipresent. 

Apart from hazards to our health, Electromagnetic Interference (EMI) is detrimental to the proper functioning of most electrical, electronic, IT, ITES, ICT, communication and technology-based systems and may cause malfunctions and even potentially disastrous and fatal accidents.

The book being reviewed – EMC for Product Designers by Tim Williams – is one of the most comprehensive reference books I have read on the subject of the Design Management aspects of Electromagnetic Interference and Electromagnetic Compatibility [EMI / EMC].

The book comprises sixteen chapters arranged in three parts:

1. Legislation and Standards
2. Testing
3. Design

The author lucidly covers most micro and macro aspects of EMC Management in meticulous detail.

The logical sequence of topics, clear diagrams, tables and illustrations facilitate easy understanding of this complicated subject.

The Design Checklist, interesting Case Studies and useful mathematical formulae in the appendices and the extensive bibliography add value to this reference book.

Whilst the earlier chapters provide an excellent understanding of the EMC Standards and the basic theoretical principles of EMI / EMC, the “meat” of the book lies in the chapters on Systems EMC and EMC Management which encapsulate all relevant facets of EMC in a holistic manner.

I wish the author had included a detailed chapter on Electromagnetic Health Hazards and mitigation techniques. Electromagnetic Pollution (Electropollution) the most vital topic concerning all human beings seems to have not been accorded the due importance it deserves and I hope the author presents a more holistic and systemic view of EMC and includes a comprehensive chapter on pertinent aspects of Bio-electromagnetics, Thermal and Athermal EMR Hazards and their mitigation in the next edition.

I commend this book – it is an excellent reference book for Electrical, Electronic, Telecommunication and IT Engineers and Managers, Designers, Students, practicing professionals in the field and a useful addition for all engineering and technical libraries.

INFORMATION SYSTEMS

Book Review

Title: Information, Systems and Information Systems – making sense of the field

Authors: Peter Checkland and Sue Howell

John Wiley & Sons (1988)

ISBN 0-471-95820-4

  

[Reviewed by Vikram Waman Karve]

   

Information Technology ( IT ) is the buzzword of today. 

IT is ubiquitous; almost everyone is connected with IT in some way or the other. 

A few years ago, till the nineteen eighties, there were courses in Electrical, Electronics, Communications and Telecommunications Engineering and later in Computer Science and Engineering, but now there are dedicated courses in Information Technology, and almost all Engineers, and even others, irrespective of their specializations, are rushing to take up jobs in IT and IT Enabled Services. 

The Management guys have also joined the fray and added a “management” dimension to IT by offering MBA courses in “IT Management”.

What exactly is IT? 

Maybe the phrase “IT” was coined to mark the convergence of two technologies that had been traditionally separate: “Computing” and “Communications” and the confluence of several streams of development including electronics, microelectronics, computer science, telecommunications, software engineering and systems analysis.

There are a large number of books and extensive literature on the content of IT. 

This book is a significant treatise on the context of IT. 

The principal author Peter Checkland is a pioneering researcher in the field of Systems Engineering and Management and has developed breakthrough concepts like Soft Systems Methodology [SSM] and written the seminal classic “Systems Thinking, Systems Practice”. The co-author Sue Holwell has a rich and varied professional experience in systems design and implementation, information strategy and communication networks.

This book has eight chapters arranged in four parts. 

In the first part on “The Field of Information Systems and its Problems” the authors deliberate on the basic concepts pertaining to Information Systems [IS] and Information Technology [IT], distinguish between the “Hard” (objective positivistic scientific) and “Soft” (subjective interpretative) schools of thought in the context of Management Information Systems [MIS], and introduce the reader to the fundamentals of Soft System Methodologies [SSM].

The “meat” of the book is in Part Two whose two chapters elucidate on the application of the developed Information System Management concepts to organizations and describe the “information continuum” – the linkages between data, information and knowledge. Parts Three and Four substantiate these hypotheses with experiential examples from as early as World War II and drives home the point that the evolution and development of the science of Information Systems [IS] owes nothing to computers which did not exist in 1940, makes it clear that IS is not the same as IT, reminds us that computers are a mere means of IS, and cautions us against falling into the trap of “technological determinism” resulting from the prevalent propensity to overly focus on computer-based IT and allow technology to take charge of our actions.

The book is aptly adorned with simple illustrations which facilitate ease of understanding. As the dust jacket says, the book is a work of conceptual cleansing and presents a well-argued account of IS and IT which is both holistic and coherent. I recommend this remarkable book to IT, Engineering and Management students and professionals – reading it will certainly enhance their conceptual understanding of Information Systems and Technology.

EMBEDDED SYSTEM DESIGN - A Useful Book

Book: Embedded System Design - A Unified Hardware / Software Introduction
Authors: Frank Vahid, Tony Givargis
Publication: John Wiley and Sons (Asia) Pte Ltd, Singapore, 2002
ISBN 9971-51-405-2
Pages: 324.

[Reviewed by Prachi A. Deshmukh and Vikram Karve]

Once, there was a conversation going on between three ladies. They were discussing on something very seriously. Each of them was telling her own experience and others were listening to the speaker very carefully. They were neither discussing about some TV serial, nor about the latest fashions. Their topic was regarding cooking. (But they were not discussing culinary recipes!). The three ladies were from three different generations – the first an 80 years old Granny, the second her 56 years old mother and the third the 28 years old daughter. They were discussing how the kitchen has been changed. Conclusion of their discussion was that, now cooking is a task of few minutes. Mixer, food processor, microwave oven, dishwasher etc. are there waiting for your orders!

Not only in kitchen, but everywhere one can see things are becoming easier and simpler. Those who are born after 1980s can experience the changes happening around themselves. Now there is no need to make your hands panic by washing the clothes. Washing machine will do it for you!

Do you want to listen to music of your choice? An MP3 player can store thousands of songs of your choice. If you want to convert your beautiful moments into sweet memories, then digital camera is there for your help.

Are you planning to go for shopping? No need to carry money with you. Credit card will maintain your account.

All these examples look unrelated to each others, but there is some relation in them. ATM, barcode scanner, cell-phone, digital camera, fax machine, home alarm system all are totally different from each others but they do have one thing common in them. All of them are embedded systems. Now the question arises ’What does an embedded system actually mean?’

In simple words, Embedded System is a computing system which does a specifically focused job. It’s nearly any computing system other than a desktop computer. We can not be unaware of it because embedded systems are part of our day to day life. We find them almost everywhere.

That’s why one must study about embedded systems, especially if you are aspiring to be an Electronics, Communications, Computer Engineer or IT Professional. For those who really want to know about embedded systems, a good book to start off with is ‘Embedded System Design- A Unified Hardware/ software Introduction ’ by Frank Vahid and Tony Givargis.

The book is actually an introductory book which makes us familiar with the basics of embedded systems, the hardware for them, the software, peripherals, memory and interfacing. This book is also helpful for those students who are going to take more specialized courses. To understand this book one needs the basic knowledge of electronics, flowcharts and algorithms.

The book shows its usefulness and applications starting from the cover itself. The picture on the cover shows all the applications in our day-to-day life which we find in home as well as outside our homes. A simple picture tells us how important to study the embedded systems.

The content in the book is divided into 11 Chapters. The first chapter introduces us with the basics of embedded systems. We become familiar with the Optimizing Design Metrics, processor technology, IC technology, design technology and trade offs.

In second chapter we learn about custom single purpose processors: Hardware. We learn about the combinational logic, sequential logic, custom single purpose processor design, RT level custom single purpose processor Design and the optimizing custom single purpose processors. If the reader knows about the transistors, logic gates and flowcharts then it will be easier to understand this chapter.

In third chapter the authors introduce us with the General Purpose Processors: Software. Here we learn the basic architecture of the general purpose processor, its operation, developing environment, ASIPs, General Purpose processor Design and about the selection of a processor.

In fourth chapter we study the Peripherals of standard Single-Purpose Processors like Timer, Counters, Watchdog Timers, UART, PWM, LCD controllers, Keypad controllers, Stepper motor controllers, ADC and RTC.

There are different types of memory like ROM, PROM, OTOROM, EPROM, EEPROM, FRAM, RAM, SRAMDRAM, PSRAM NVRAM etc. We learn different types of memories as well as cache memory and MMU in the fifth chapter.

In sixth chapter we study the different types of interfacings to the processors as well as arbitration, multiple Bus architectures and advanced communication principles. Here we come to know about the different types of protocols.

Digital camera is an important and interesting example of embedded systems. In seventh chapter this example is explained very briefly. Here we learn about the requirements as well as the design of an embedded system very detail. Chapter no 8 and 9 are about the state machine and concurrent process models as well as the control systems.

Chapter 10 introduces us with the IC technology. Here we learn about the VLSI IC technology, ASIC IC technology and PLD IC technology. This chapter teaches about the IC technologies briefly.

In last chapter of the book, chapter 11 we learn about the techniques like Automation, Verification, Reuse, Design Process Models. At the end of this chapter we find the book summary. It gives us summary of the entire book in few words.

In appendix A the website is given which includes important information regarding the embedded systems. Also included are chapter wise lab resources. As embedded system is combination of both - hardware and software, it is very important to perform the practical experiments to understand the concepts.

This book is not just a simple basic book but is adequate for a complete course in embedded systems. The authors have maintained a smooth flow throughout the book. The language is easy to understand. One special feature of this edition of the book is that it has been designed specially for the students in developing countries.

An ideal textbook, this book may prove even more useful to understand the importance of embedded systems if some more applications of embedded systems were illustrated. Maybe further editions can be made more attractive by adding the photographs of the examples of embedded systems.

The summary at the end of every chapter give the important part of each chapter in brief. The review questions are helpful to prepare for the subject. The References and further reading are useful for those interested in a more detailed study of the subject.

We feel that this book may be extremely useful for students, engineers, technologists and professionals interested in the fascinating field of Embedded Systems.
