Abstract

Sliding weighted Fourier transformer for the transformation of rows of numbers, in the process of which a new Fourier transformation is performed by making a correction to the previously determined Fourier transformation. In order to obtain a weighted Fourier transformation, the Fourier transformation is split-up in three transformation which can also be corrected and which together make up the weighted Fourier transformation.
