Abstract
This paper explains some familiar but intricate circuit forms that are used to implement the fast Fourier transform. They are shown to be solutions to a recursion equation that defines the transform. An earlier paper [6] showed that the essence of the fast Fourier transform is captured by an equation characteristic of divide-and-conquer algorithms. Butterfly circuits have been shown [8] to be solutions to such equations, and in this paper solutions are derived to the particular equation defining the fast Fourier transform.
