as executables so they can be run directly without a Labview license. The software is available on both
the Wiley Student and Instructor’s websites.
NEW TO THIS 5
TH EDITION
With this 5
th edition, we have new or expanded material on a number of topics. As highlights:
We introduce Monte Carlo simulation methods in Chapter 4 and tie their use with uncertainty estimations in Chapter 5.
Treatment of uncertainty analysis in Chapter 5 has been updated to include changes in test standards
methodology relative to ASME PTC 19.1 Test Uncertainty and the International Standards Organization
(ISO) Guide to Uncertainty in Measurements. These changes have been carried into the other chapters
both in language and in example problems. Where we deviate from the methodology of the Standards,
we do so for pedagogical reasons.
Discussion has been added on using rectangular (uniform) distributions in uncertainty estimation.
The treatment of non-symmetric uncertainty intervals and methods for treating correlated errors in
Chapter 5 has been expanded and revisited in other chapters.
We have updated our symbol usage for closer consistency with the standards.
We have added a section presenting image acquisition and processing using digital techniques in
Chapter 7.
We have changed our presentation of pressure transmission line effects to make better use of the lumped
parameter methods of Chapter 3 that engineering students are familiar with, including discussion of the
ideal elements of inertance, resistance, and compliance.
We have revised our treatment of Butterworth filters, including added coverage, in Chapter 6.

SUGGESTED COURSE COVERAGE
To aid in course preparation, Chapters 1 through 5 provide an introduction to measurement theory with statistics
and uncertainty analysis, Chapters 6 and 7 provide a broad treatment of analog and digital sampling methods,
and Chapters 8 through 12 are instrumentation focused.
Many users report to us that they use different course structures, so many that it makes a preferred order of
topical presentation difficult to anticipate. To accommodate this, we have written the text in a manner that allows
any instructor to customize the order of material presentation. While the material of Chapters 4 and 5 are integrated
throughout the text and should be taught in sequence, the other chapters tend to stand on their own. The text is
flexible and can be used in a variety of course structures at both the undergraduate and graduate levels.
For a complete measurements course, we recommend the study of Chapters 1 through 7 with use of the
remaining chapters as appropriate. For a lab-course sequence, we recommend using chapters as they best
illustrate the course exercises while building complete coverage over the several lab courses normally within a
curriculum. The manner of the text allows it to be a resource for a lab-only course with minimal lecture. Over
the years, we have used it in several forums, as well as professional development courses, and simply rearrange
material and emphasis to suit the audience and objective.
We express our sincerest appreciation to the students, teachers, and engineers who have used our earlier
editions. We are indebted to the many who have written us with their constructive comments and encouragement.
