Complex time-domain data--the signal’s acceleration over time--is generally a combination of many sinusoidal waves. As such, engineers cannot use time-domain data to observe the frequency content and must convert the data into the frequency domain. This video illustrates the impact of doing so.
Vibration Research University offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle sine testing, random testing, preventative maintenance, multi-axis testing, calibration, and more.
