Joint Time-Frequency Analysis (JTFA)

Joint Time-Frequency Analysis (JTFA) describes the frequency components or frequency spectrum of a signal over a defined period of time. Therefore, the display shows the changes in amplitude of the frequency components versus time.

In the attached document, we will briefly introduce you to the JTFA analysis basics.

Note: LabVIEW and LabWindows/CVI both offer a solution for measuring transient signals and signals whose frequency components change over time. The Signal Processing Toolset consists of three major areas:
  • Joint time-frequency analysis (JTFA)
  • Super-resolution spectral analysis
  • Wavelet analysis
