Find the 4-point DFT of the sequence x[n] = [3, 2, 2, 5] using the DIT-FFT algorithm and plot the amplitude spectrum.
Added by Kelly A.
Step 1
Step 1: The DIT-FFT algorithm is a divide-and-conquer algorithm that recursively breaks down a DFT of any composite size (N = 2^m where m is an integer) into many smaller DFTs of sizes N/2, then combines those DFTs to get the final DFT. Show more…
