Vibration analysis is a process that monitors vibration levels and investigates the patterns in vibration signals. It is commonly conducted both on the time waveforms of the vibration signal directly, as well as on the frequency spectrum, which is obtained by applying Fourier Transform on the time waveform.

What are vibration signals?
What is a Vibration Signal? Vibration is a mechanical event in which oscillations occur about an equilibrium point, and the time series that carries the information of those oscillations, is called vibration signal. These oscillations from the equilibrium point need to be acquired at a high sampling rate.
What are the 3 important parameters used to measure vibration?
There are three main parameters that are measured to evaluate the vibration characteristics of any dynamic system as: acceleration, displacement and velocity.
What is FFT analysis in vibration?
The fast Fourier transform (FFT) is an efficient algorithm used to compute a discrete Fourier transform (DFT). This Fourier transform outputs vibration amplitude as a function of frequency so that the analyzer can understand what is causing the vibration.
