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.
