[PDF] FFT Tutorial
When the FFT is computed with an N larger than the number of samples in x[n], it fills in the samples after x[n] with zeros Example 2 had an x[n] that was 30 samples long, but the FFT had an N = 2048 When Matlab computes the FFT, it automatically fills the spaces from n = 30 to n = 2047 with zeros
