Hi,
I have a time series of accelerations (acceleration versus time) and I need to convert it to acceleration versus frequency. At a glance my first idea was to take the Fourier transform of the data set which would give power versus frequency and then use some kind of existing proportionality to get acceleration versus frequency. The first step (taking the Fourier transform) is trivial but I'm not sure how to proceed after that. Furthermore, I'm not even sure if this approach is correct. Could someone who has done something similar to this in that past give me an idea how to proceed? Thanks.
