Conversion of Time domain data to frequency domain data on HYPERGRAPH

Dear Forum Members,

 

I would like to bring forward an issue that I am facing for the conversion of time domain data (time vs accln.) to frquency domain (Frequency vs PSD accln. in g²/hz)

I have looked into several documentations online regarding this and I was unable to land on a concrete method to get this conversion done.

I was able to import the data which has time(s) in x-axis and convert into frequency on the x-axis. Then, moving onto the accleration data which is on y axis, I was unable to find methods in to convert into PSD accln.. I used several math functions like PSD, FFTMAG, Hanning. I was unable to get the data in the format I wanted it to be.

 

I thank you in advance, if you could find some ways to help me out here with this issue.

 

I have also attached the screenshot of the time domain data and also the way in which I approched this problem on the hypergraph.

i. Defining the curve

ii. Selecting the y axis and

iii.  Selecting the desired function for the transformation

 

Thanks and Regards,
