  • Abstract
    This paper includes a brief tutorial on digital spectrum analysis and FFT-related issues to form spectral estimates on digitized signals. Some review of the DFT has been presented, and some discussion on the computational advantages of the FFT calculation has also been presented. Finally, the main considerations on windowing and window characteristics have been briefly discussed.
