Praise for Noise Reduction Techniques IN electronic systems
"Henry Ott has literally 'written the book' on the subject of
EMC. . . . He not only knows the subject, but has the rare ability
to communicate that knowledge to others."
--EE Times
Electromagnetic Compatibility Engineering is a completely
revised, expanded, and updated version of Henry Ott's popular book
Noise Reduction Techniques in Electronic Systems. It reflects the
most recent developments in the field of electromagnetic
compatibility (EMC) and noise reduction and their practical
applications to the design of analog and digital circuits in
computer, home entertainment, medical, telecom, industrial process
control, and automotive equipment, as well as military and
aerospace systems.
While maintaining and updating the core information--such
as cabling, grounding, filtering, shielding, digital circuit
grounding and layout, and ESD--that made the previous book
such a wide success, this new book includes additional coverage
of:
Equipment/systems grounding
Switching power supplies and variable-speed motor drives
Digital circuit power distribution and decoupling
PCB layout and stack-up
Mixed-signal PCB layout
RF and transient immunity
Power line disturbances
Precompliance EMC measurements
New appendices on dipole antennae, the theory of partial
inductance, and the ten most common EMC problems
The concepts presented are applicable to analog and digital
circuits operating from below audio frequencies to those in the GHz
range. Throughout the book, an emphasis is placed on cost-effective
EMC designs, with the amount and complexity of mathematics kept to
the strictest minimum.
Complemented with over 250 problems with answers,
Electromagnetic Compatibility Engineering equips readers
with the knowledge needed to design electronic equipment that is
compatible with the electromagnetic environment and compliant with
national and international EMC regulations. It is an essential
resource for practicing engineers who face EMC and regulatory
compliance issues and an ideal textbook for EE courses at the
advanced undergraduate and graduate levels.
