EMC Book Receives Scholarly Publishing Award
From: Interference Technology eNews, March 4, 2010
“Electromagnetic
Compatibility Engineering,” written by Henry Ott and published by
John Wiley & Sons Inc., received a PROSE Award for 2009 in the
subject of Engineering & Technology. The PROSE Awards annually
recognize the best in professional and scholarly publishing by bringing
attention to distinguished books, journals, and electronic content in
over 40 categories. The awards have been judged by peer publishers,
librarians, and medical professionals since 1976.
New Partitioning and Layout of Mixed-Signal PCB Seminar
Preventing digital logic ground
currents from contaminating low-level analog signals on a mixed-signal
PCB can be a difficult problem. This is especially true on boards
with multiple ADCs. Many people suggest splitting the ground
plane in order to isolate the digital ground from the analog
ground. Although the split-plane approach can be made to work it
has many potential problems. The pitfalls, as well as the
benefits, of splitting ground planes are examined.
By understanding how and where
high-frequency ground currents flow, and by using some basic principles
of Electromagnetic Compatibility (EMC) we are able to develop an
approach to controlling these currents while still maintaining a single
contiguous ground plane.
This one-day presentation
demonstrates that component placement, partitioning, and proper PCB
topology, combined with routing discipline, are the keys to success in
laying out a mixed-signal PCB. Mixed-Signal PCB Seminar Outline.
Antenna Design Simplified Seminar Offered by Henry Ott Consultants
Why is Henry Ott Consultants (an EMC training and consulting
organization)
offering a course on Antenna Theory? Well, if a product, or PCB,
or cable radiates or is susceptible to electromagnetic energy, it is
acting
as an antenna. Besides, antennas are used in EMC testing, both emission
and susceptibility. In all these cases an understanding of some
basic
antenna theory would be very useful to the engineer or
technician.
However, the way that antenna theory is taught in schools and
universities
- it is too theoretical and abstract to be very helpful. Hence
our
course, Antenna Theory Simplified.
European Union EMC
New
EMC Directive (2004/108/EC)
A new updated version of the fifteen year old EMC Directive
(89/336/EEC) was published in the Official Journal of
the European Communities on December 31, 2004 as Directive 2004/108/EC. The new
directives protection requirements remain essentially the same,
however, most other aspects of the
directive have been completely rewritten. See EMC Regulations for more information.
Revised
EMC Directive Standards List
An
updated
list of harmonized standards under the new EMC directive
2004/108/EC (previously 89/336/EMC)
along with their effective dates was published in the Official
Journal
the European Communities (OJ) on November 4, 2008.
The
list replaces all previous lists published in the OJ.
The list is available at: http://europa.eu.int/comm/enterprise/newapproach/standardization/harmstds/reflist/emc.html
