Am I correct in saying that when taking the DFT using the FFT, it is sometimes useful to create higher definition in frequency domain for plotting.  I have noticed that there are some scientists that believe that the straight DFT is as fine of resolution as the information can give.  Are there situations where we sample the continuous frequency spectrum using the unaltered DFT and sample in such a way as to miss a peak, creating a peak with larger tails?  It seems like the DFT is just a sample of the true spectrum, and there is something to gain by increasing the definition of the DFT by padding with zeros.  If anyone is interested in answering this, I would be most grateful.  Thank you for considering my post.
