variable sampling frequency-FFT

Hello all, First a little bit of background: I have constructed a continuous time signal from the output of a Sigma-Delta modulator whose output is varying frequency.. Therefore, this signal has varying sampling frequency(which can take 4 values)..I am trying to find the FFT(rather plot the spectrum) of that signal... For that I looked around in the forums and found that we use NDFT for that... but all the discussions I have found are extremely confusing.. Can anyone kindly clarify me of the procedure to follow to obtain the spectrum of such a signal..
Thanks in advance..
