WebMay 7, 2024 · Its length is 4 and it’s periodic. We can observe that the circular convolution is a superposition of the linear convolution shifted by 4 samples, i.e., 1 sample less than the linear convolution’s length. That is why the last sample is “eaten up”; it wraps around and is added to the initial 0 sample. WebIn mathematics, the discrete Fourier transform ( DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), …
