In this work three structures are presented for evaluating in real time the discrete Fourier transform (DFT) on successive sections of a sampled signal. Each section consists ofNelements and two successive sections are staggered ofM leq Nelements. Each structure evaluatesN/MDFT coefficients at every step and requires about(N/(2M)) log_{2} 4Mmultipliers.
