Blackman–Tukey transformation
From Wikipedia, the free encyclopedia
The Blackman–Tukey transformation (or Blackman–Tukey method) is a digital signal processing method to transform data from the time domain to the frequency domain. It was originally programmed around 1953 by James Cooley for John Tukey at John von Neumann's Institute for Advanced Study as a way to get "good smoothed statistical estimates of power spectra without requiring large Fourier transforms."[1] It was published by Ralph Beebe Blackman and John Tukey in 1958.
