WebOct 19, 2024 · Comparing the DFT of x2(n) x 2 ( n) with the DTFT of x(n) x ( n), we can easily verify that the DFT of the zero-padded signal gives four samples of the DTFT in contrast to the DFT of x1(n) x 1 ( n) which gives only three samples. Hence, the zero-padding technique increases the number of samples that we get from a particular DTFT. Web14.
