Pagination or Media Count:
An analyzer is described which performs directly 2-dimensional Fourier summations of the type sum over h sum over k Fhkcos 2 pihXkY. The analyzer also evaluates sine summations and some 3-dimensional summations. The device accomodates values of Fhk or - 1-99, h -15 to 15, k 0 to 15 for X and Y 136 of the repeat distance. The operation of the analyzer is illustrated by an example.
