Introduction to the Radix 2 FFT

Introduction to Fast Eigenspace Methods
  • James K. Beard


The FFT first emerged as an integrated, well-defined algorithm in Cooley and Tukey’s classical 1965 paper13. Early implementations were principally power of two algorithms, but, in 1969, Singleton published a paper exploiting Cooley and Tukey’s algorithm using a variable radix14. Bergland15,16 has shown advantages for radix 4 and radix 8 FFTs, which are commonly exploited in modern implementations.
