THE
BIRTH OF WILLIE
We're asked
often about the origins of Willie, our lab robot. So,
we're writing an online book about him! We've
published the prologue online.

ESPRESSO ENGINEERING
Take a peek at our
new desktop video series exploring today's challenges and tomorrow's
solutions in the product engineering arena.
This three-day course
covers the practical aspects of noise and interference control in
electronic systems. It will provide the participants with a
working knowledge of electromagnetic compatibility principles.
Emphasis is on cost effective EMC design for digital systems. The
commercial and industrial aspects of EMC Engineering are
emphasized. The amount and complexity of mathematics will be kept
to a minimum, and ideas will be illustrated with examples of
actual case histories..
Who Should Attend
This course is directed towards electrical
engineers. However, mechanical engineers, reliability and
standards engineers, technical managers, systems engineers,
regulatory compliance engineers, technicians, and others who need
a working knowledge of electromagnetic compatibility engineering
principles will also benefit from the course.
The participants should receive from this course knowledge
necessary to design electronic equipment which is compatible with
the electromagnetic environment, and is in compliance with
national and international EMC regulations.
Henry W. Ott is President and Principal Consultant of Henry Ott
Consultants, an EMC training and consulting organization. He
has literally "written the book" on the subject of EMC, and is
considered by many to be the nation's leading EMC educator. He is
the author of the popular EMC book, Noise Reduction Techniques in
Electronic Systems, (1976, 1988). The book has sold over
65,000 copies and has been translated into six other languages. In
addition to knowing his subject, Mr. Ott has the rare ability to
communicate that knowledge to others.
Mr. Ott's newly published (Aug. 2009) 872-page book,
Electromagnetic Compatibility Engineering is the most
comprehensive
book available on EMC. While still retaining the core information
that made Noise Reduction Techniques an international
success, this new book contains over 600 pages of new and revised
material.
Prior to starting his own consulting company, Mr. Ott was with
AT&T Bell Laboratories, Whippany, NJ, for 30 years, where he
was a Distinguished Member of the Technical Staff and a consultant
on EMC.
Mr. Ott is a Life Fellow of the IEEE. For over 20 years, Mr. Ott
has served the EMC Society in various capacities including:
membership on the Board of Directors, Education Committee
Chairman, Symposium Committee Chairman and Vice President of
Conferences. He is also a member of the ESD Association and a
iNARTE certified ESD engineer. He is a past Distinguished
Lecturer of the EMC Society, and lectures extensively on the
subject of EMC.
The following will be covered
during the three day course:
• CABLING
Electric and magnetic field coupling, crosstalk. Cable types: coax, twisted pair and ribbon cables. Cable shielding and terminations.
• GROUNDING PRINCIPLES
Why do we ground? Ground systems: single point, multipoint, hybrid. Ground loops. Return current paths, split reference planes. EMC grounding philosophy. AC power grounds.
• DIGITAL LAYOUT & GROUNDING
Noise sources, PCB layout, power distribution, ground grids, characteristics of ground planes. Decoupling capacitors: value, placement, resonance and limitations.
• HIGH SPEED DIGITAL DECOUPING
Alternative decoupling methods, use of distributed decoupling capacitance, power supply isolation, effect of paralleling capacitors. Embedded PCB capacitance.
• COMMON-MODE FILTERING
Basic C-M filter theory. Filter source and load impedances. Single and multi-stage filters. Ferrite chokes versus shunt capacitors. Effectiveness of various filter configurations. Filter mounting and layout.
• TRANSMISSION LINES
What is a transmission line? Transmission-line effects, transmission-line radiation, and matching. How currents flow on transmission lines. Series, shunt and AC terminations. Simulation.
• MIXED SIGNAL PCBs
Defining the problem, A/D converter requirements, return current paths, split ground planes, PCB partitioning, bridges & moats, routing discipline.
• RF & TRANSIENT IMMUNITY
RF immunity: circuits affected, PCB layout, audio rectification, RFI filters. Transient immunity: circuits affected, the three-prong approach, keeping transient energy out, protecting the sensitive devices, designing
software/firmware for transient immunity.
• CONDUCTED EMISSION
AC power line conducted emission models, switching power supplies, parasitic capacitance, layout.
Common-mode and differential-mode conducted emission, common-mode chokes, saturation. Power line filters.
• SHIELDING
