The story of three students' discovery of the elationship between continuous and discrete transforms ~~ J. R. DELLER, JR. iscrete Fourier techniques are increasingly being taught as material detached from fundamen-D tal 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. This article tells the story of
