Thanks to everyone for all of their help on this - I actually managed to solve the problem myself before Philippe posted his solution and so i understand it quite well now. However - having Philippe's solution will be a great help to me in seeing how other people do things in Mathematica - so thanks :) For the record a very useful reference on discrete fourier transforms can be found in Numerical Recipies (also available in full online) - though i have to admit that I had difficulty finding anything to do with their use in numerical differentiation. Many texts said something on the lines of 'DFT's are commonly used for numerical differentiation' - and then failed to mention anything about this. Does anyone have a good reference to a text that explains this application well? Thanks again - Mike
