Course Description
The course includes viewgraph presentations
as well as hands-on software training.
1. Each student must bring a notebook
PC with Windows 95, 98, ME, NT, 2000 or XP operating system.
2. Each student will receive a copy of
EasyPlot software.
3. Each student will receive software
programs which perform the following calculations: power spectral
density (PSD), Fast Fourier Transforms (FFT), shock response
spectrum (SRS), and digital filtering.
4. Students will receive time history
data samples so that they can practice using the software programs.
5. Students are also welcome to bring their own data samples.

Prerequisites
Engineers, Technicians, and Managers who
must analyze or interpret shock and vibration data or specifications
will benefit from this course.
A degree in engineering or technology is helpful but is not required.
The course is now open to foreign students.
