Re: derivative of discrete fourier transform interpolation

Hi all,
Just a question with regards to the derivative of a DFT.
I am not a mathematician, just an engineer with a math problem  so I will have to go slowly:
I wish to compute the derivative of a DFT. How do I go about doing this? (Specifically, I require some uncertainty propagation analysis with the Taylor Series Method, and my funtion is actually the Discrete fourier transform of a set of sampled data).
Strictly speaking the TSM requires the partial derivatives of the function in question i.e. the DFT in my case.
If anyone could help I would appreciate it...maybe even some info on references for this sort of problem.
Thanks Darth
