Performing FFT

Aditya Hegde_22173

I have performed FFT using hypergraph and I am able to get the frequency vs amplitude plots as shown below. But the frequency steps I am getting are very random and is there any way to specify the frequency steps as per requirement (eg: 0. 0.5, 1, 1.5Hz) in the hypergraph itself.   

 

Thanks and Regards

Hello Aditya 

Can you refer to Linear interpolation function in hypergraph (https://2022.help.altair.com/2022/hwdesktop/hwd/topics/reference/math/lininterp.htm)

This would resample the frequency and amplitude based on a new frequency values (vector) .

Thanks
