    Abstract

    A formalism for obtaining the minimum variance estimates and covariaces of the diffraction peak intensities from the total scattering data synthetized with continuous frequency filters by the reverse Fourier method is presented. It is shown that with a properly chosen bandpass filter several advantages are obtained over the low-pass filters exclusively applied up to now. These are: elimination of the background contributions, improvement in the resolving power almost by factor 3, reduced sensitivity to possible non-idealities of the frequency filter and the possibility of eliminating the higher harmonic contributions.
