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.
