Journal ArticleDOI
The re-discovery of the fast Fourier transform algorithm
TL;DR: The author's own involvement and experience with the FFT algorithm is described, which led to an unfolding of its pre-electronic computer history going back to Gauss.
Journal ArticleDOI
Fourier transform and convolution subroutines for the IBM 3090 Vector facility
Ramesh C. Agarwal,J.W. Cooley +1 more
TL;DR: A set of highly optimized subroutines for digital signal processing has been included in the Engineering and Scientific Subroutine Library (ESSL) for the IBM 3090 Vector Facility with speedups of up to 9½ times over scalar performance on the 3090.
Journal ArticleDOI
The application of the fast Fourier transform algorithm to the estimation of spectra and cross-spectra
TL;DR: Alternative methods for the estimation of spectra are described and compared and general questions of statistical variability, the use of regression methods to smooth the periodogram, and use of time sectioning of the data to either smooth or to investigate non-stationarities in the data are discussed.
Journal ArticleDOI
New scalar and vector elementary functions for the IBM system/370
Ramesh C. Agarwal,J.W. Cooley,Fred G. Gustavson,James B. Shearer,Gordon Robert Slishman,Bryant Tuckerman +5 more
TL;DR: Algorithms have been developed to compute short- and long-precision elementary functions: SIN, COS, TAN, COTAN, LOG, LOG10, EXP, POWER, SQRT, ATan, ASIN, ACOS, ATAN2, and CABS, in scalar (28 functions) and vector (22 functions) mode.
Journal ArticleDOI
How the FFT gained acceptance
TL;DR: The history of the fast Fourier transform is recounted, beginning with the publication and subsequent development of the concept by R.L. Garwin in the 1960s and the activities of the IEEE ASSP digital signal processing committee in promoting the use of the technique.
