WebJun 25, 2010 · The outputs of the DFT are samples of the DTFT, and in this case the sample locations just happen to align with the locations of four zeros in the DTFT. You can get a finer sampling (and a much nicer-looking DTFT plot) by zero-padding. Here I'll use the zero-padding syntax of fft. N = 256; X = fft(x, N); plot(abs(X)) ... WebIDE n-0 Describe how you do the 8-point DFT calculation. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core …
