WebMar 15, 2010 · This syntax computes the P-point DFT of x by using zero-padding. Let's try a 50-point DFT. P = 50; Xp = fft (x, P); w_k = (0:P-1) * (2*pi/P); X = fft (x); plot (w, abs (X_dtft)) hold on plot (w_k, abs (Xp), 'o' ) hold off If you've ever wondered what that whole zero-padding business was all about with Fourier transforms, now you know. WebNov 21, 2015 · Usually, people like to plot a good approximation of the DTFT (or maybe even the CTFT) using the FFT, so they zero-pad the input with a huge amount of zeros (the function fft () does this on it's own) and then they use the fftshift () function to plot between -pi and pi. In other words, use fftshift (fft ()) for plotting, and fft () for the math!
