Abstract: | Summary In this paper fundamental theorems are proved for computing the so called index transforms which mapm-dimensional discrete Fourier transform operator (DFT) ton-dimensional one. These transforms are based on mapping indexes of input and output sequences of DFT operators. The general form of these transforms is found and the necessary and sufficient conditions of their existence are described. |
