DFT Processing

2012 
in this project it was explored how the Discrete Fourier Transform (DFT) signal affects as increase the number of sampling points on DTFT. The numerical method used is zero-padding. It can be found that zero-padding is an efficient way to make the DFT more accurate in terms of diagrams. In addition to that, window method is introduced to modify the signals. Hamming window is a good approach to minimize the "side lobes" around the main lobes. Above all, in terms of the theorem of Fourier series, the project generated the modified Discrete Fourier Transform, and analyzed the relationship between DTFT and CTFT via mat lab tools.
