Assignments
Assignment #1
 Do the assigned reading.
 FB Problems 1.2, 1.5, 1.10, 1.21, 1.46.
 Take the weekly homework quiz.
Assignment #2
 Do the assigned reading.
 FB Problems 2.5, 2.7, 2.11, 2.17, 2.18, 2.20, 2.28.
 Take the weekly homework quiz.
Assignment #3
 Do the assigned reading.
 Do the exercise of Lecture 02.07 (encoding and decoding with DFTs) from the Measurement notes. Here are two hints. (1) using a window function makes things better … but you’ll need to scale by a factor (e.g.
hanning
must be rescaled by2
because its “gain” is1/2
) and (2) we only want a onesided spectrum (positive frequencies), so multiplying by another factor of2
and selecting the first “half” of thefft
output is necessary.  Take the weekly homework quiz.
Assignment #4
 Do the assigned reading.
 FB Problems 3.4, 3.7, 3.10, 3.16, 3.24, 3.29, 3.45.

 FB Problems 3.26, 3.31, 3.33, 3.47, 3.48.
 Take the weekly homework quiz.
Assignment #6
 Do the assigned reading.
 Write a MATLAB, Python, or Mathematica program that finds and plots (via a partial sum) the steadystate solution for a secondorder measurement system characterized by damping ratio $\zeta = 0.707$ natural frequencies $f_n \in \{50,150,450\}$ Hz subjected to an input triangle wave of amplitude $3$ and period $0.05$ s. Why are these results so different?
 Take the weekly homework quiz.

Resources
Class resources will be posted here throughout the semester.
Video lectures
Most lectures will be available online on my YouTube channel. I recommend subscribing and familiarizing yourself with the playlist for this course.
Slack
Everyone is required to join the messaging service called “Slack.” We’ll use it to communicate with each other during the semester. The Slack team you need to join is called me3152017F. That was a signup link, right there.
Homework, quiz, & exam policies
Homework & homework quiz policies
Weekly homework will be “due” on Wednesdays, but it will not be turned in for credit. However — and this is very important — each week a quiz will be given that will cover that week’s homework.
Quizzes will be available on moodle each week (as early as I can get them up), and must be completed by Sunday (before midnight). Late quizzes will receive no credit. Multiple attempts may be made on the quizzes (you will receive your mean grade).
Working in groups on homework is strongly encouraged, but quizzes must be completed individually.
Exam policies
The midterm and final exams will be inclass. If you require any specific accommodations, please contact me.
Calculators will be allowed. Only ones own notes and the notes provided by the instructor will be allowed. No communicationdevices will be allowed.
No exam may be taken early. Makeup exams require a doctor’s note excusing the absence during the exam.
The final exam will be cumulative.
Grading policies
Total grades in the course may be curved, but individual homework quizzes and exams will not be. They will be available on moodle throughout the semester.

Academic integrity policy
Cheating or plagiarism of any kind is not tolerated and will result in a failing grade (“F”) in the course. I take this very seriously. Engineering is an academic and professional discipline that requires integrity. I expect students to consider their integrity of conduct to be their highest consideration with regard to the course material.
Correlation of course & program outcomes
In keeping with the standards of the Department of Mechanical Engineering, each course is evaluated in terms of its desired outcomes and how these support the desired program outcomes. The following sections document the evaluation of this course.
Desired course outcomes
Upon completion of the course, the following course outcomes are desired:
 students will have a clear and thorough understanding of concepts, principles, and methods of measurement, instrumentation, and experimental design;

students will be familiar with the operation and uses of a number of measurement systems, including the following:
 electrical (e.g. thermistor, strain gage, transducer, displacement indicator, tachometer),
 fluid mechanic (e.g. pitot tube, flowmeter),
 optic (e.g. anemometer, velocimeter, IR detectors), and
 thermoelectric (e.g. thermocouple);
 students will understand basic signal conditioning, processing, and recording;
 students will understand instrumentation calibration and response;
 students will be able to analyze designstage uncertainty;
 students will understand signal characteristics, the Fourier transform, and digital signal analysis;
 students will understand the basics of probability, statistics, uncertainty analysis, regression, and correlation;
 students will be able to write a technical report; and
 students will understand and be able to communicate the broader context of the course material.
Desired program outcomes
The desired program outcomes are that mechanical engineering graduates have:
 an ability to apply knowledge of mathematics, science, and engineering;
 an ability to design and conduct experiments, as well as to analyze and interpret data;
 an ability to design a system, component, or process to meet desired needs;
 an ability to function on multidisciplinary teams;
 an ability to identify, formulate, and solve engineering problems;
 an understanding of professional and ethical responsibility;
 an ability to communicate effectively;
 the broad education necessary to understanding the impact of engineering solutions in a global and social context;
 a recognition of the need for, and an ability to engage in lifelong learning;
 a knowledge of contemporary issues; and
 an ability to use the techniques, skills, and modern engineering tools necessary for engineering practice
