    Provides a visual interpretation of the Cooley-Tukey family of FFT algorithms (Cooley and Tukey, 1965) in terms of the shifting properties of the Fourier-transform which equate shifts in one domain to proportional rotations in the alternative domain. This approach was proposed in an appendix to Chapter 6 of Kraniauskas (1992). The arguments presented in the article were developed with the aid of 3... View full abstract»

    Discrete Fourier techniques are increasingly being taught as material detached from fundamental continuous-time Fourier analysis. The student is left with an unclear understanding, if any, of the very significant relationships between magnitude and phase spectra generated digitally, and the continuous-time signal which is being analyzed. The present article tells the story of three undergraduate s... View full abstract»
