Logarithm of the discrete Fourier transform

Michael Aristidou and Jason Hanson

Digipen Institute of Technology, Redmond 98052, WA, USA

Abstract

The discrete Fourier transform defines a unitary matrix operator. The logarithm of this operator is computed, along with the projection maps onto its eigenspaces. A geometric interpretation of the discrete Fourier transform is also given.
