• Key Concepts: 
  Fast Fourier Transform (FFT) is a mathematical algorithm used to analyze vibration data in SAP’s PM-PDM-VA Vibration Analysis component. It is used to convert a signal from its time domain to its frequency domain, allowing for the analysis of the frequency components of the signal. 
  
  How to use it: 
  In SAP’s PM-PDM-VA Vibration Analysis component, FFT can be used to analyze vibration data. To do this, the user must first select the desired signal and then select the FFT option. The user can then adjust the parameters of the FFT algorithm, such as the window size and overlap, to get the desired results. 
  
  Tips & Tricks: 
  When using FFT in SAP’s PM-PDM-VA Vibration Analysis component, it is important to select an appropriate window size and overlap. A larger window size will provide more accurate results, but will also take longer to process. It is also important to ensure that the signal is properly filtered before running the FFT algorithm.
