"WebBasically, the SDFT comes from the observation that for two successive time instants, say n¡1 andn, the windowed sequences x(n¡1) and x(n) contain essentially identical elements. For example, if the window lengthN=16, then at the time instantn= 15, the sequence x(15) =fx(0);x(1);:::;x(14);x(15)g(4) is fed to the 16-DFT. " - Dft value of time
