Standard DIT-FFT and DIF-FFT algorithms are efficient in computing discrete fourier transform of a finite length sequence whose length can be expressed in powers of 2, but these algorithms can't be employed to compute non radix-2 length DFT'S. Hence we propose a algorithm to evaluate these ...
Python-GUI-FFT-Calculator-using RADIX Algorithm This is a Python GUI Application Developed by Anshuman Biswal to Perform Fast Fourier Transform (FFT) on a given Signal Sequence. It is written in Python 3.8 and GUI is designed in TKinter. Users can find DFT and IDFT of 4-Point,8-Point sig...
