Fourier Analysis

Nov 15, 2022 09:26 AM (3920 views)

I have a data set of 2 parameter per second and would like to perform a Fourier analysis.

Both data tends to swing and I would like to see of the period of both is in phase or not.

There is no dedicated tool in JMP for the traditional Fourier analysis. The closest tool is the Functional Data Explorer in JMP Pro.

There is a JSL FFT() (Fast Fourier Transform) function that you could use to process the signal data and then do further analysis within JMP.

JMP Time Series platform can produce Spectral Density plots. Maybe that can be useful. Here is a screenshot.
