Finite-length discrete transforms

WebDec 21, 2024 · Discrete Fourier transform of a finite length signal which saturates at non-zero value. Ask Question Asked 2 years, 3 months ago. Modified 2 years, 3 months ago. … WebWhen time is discrete, the frequency axis is finite, and vice versa. Reference develops the DFT in detail--the discrete-time, discrete-frequency case. In the DFT, both the time and frequency axes are finite in length. Table 2.1 (next page) summarizes the four Fourier-transform cases corresponding to discrete or continuous time and/or frequency.
