Abstract

The 2-D DFT is presented as two sets of 1-D DFTs. Examples of the 2-D DFT are given. The formal definitions of 2-D DFT and IDFT are presented. The computation of the 2-D DFT by the row–column method is described with examples. Finally, a comprehensive coverage of the properties of the 2-D DFT is presented with examples.
