Redundancies in the computational procedure of the FFT by which the DFT is calculated are analized and a modified algorithm to reduce redundancies is proposed. An amended FFT fortran program adopting the proposed algorithm shows that the time necessary for DFT computation is decreased about one-tenth. The proposed method can be applied to the most of other transformation algorithms.
