Tables of orthogonal comparisons for Fourier analysis have been derived from general expressions applicable to periodic data over one cycle, for equal spacing of the levels of the independent variable. The orthogonal comparisons can be used in conjunction with orthogonal polynomials to analyse factorial experiments with any number of levels and factors of periodic or polynomial type. The appropriate grouping of mean squares for significance testing is considered. A numerical example is given.
