Abstract : An analyzer is described which performs directly 2-dimensional Fourier summations of the type sum over h sum over k F(hk)cos 2 pi(hX+kY). The analyzer also evaluates sine summations and some 3-dimensional summations. The device accomodates values of F(hk) = + or - (1-99), h = -15 to 15, k= 0 to 15 for X and Y = 1/36 of the repeat distance. The operation of the analyzer is illustrated by an example.
