Hello everyone, I am attempting to perform a discrete Fourier transform on a time series using Mathematica 4.0. (I'd like to determine the period of the signal.) Unfortunately, I noticed that I cannot control the frequency resolution of this transform. I also have no idea what units the frequency is in. Do you know of any way to get around the problem? Thanks so much. Catherine Neish
