I have Frequency Weighted RMS Acceleration Data for ISO-2631-1 ride comfort analysis in time domain.
I want to compare it with ISO-2631-1 Time Exposure Limit plot by superimposing the available FWRMS acceleration above mentioned (As shown in attached Figure). So can I directly use FFT to above data to obtain it Frequency domain from Time domain and superimpose on Time Exposure Limit graph available in frequency domain?
