The table-lookup method is a convenient and very flexible way to generate high-quality sinusoidal test signals for measurements in psychoacoustics, speech perception, etc. Exact spectra of such signals, which are of great interest in experiments, are derived, and the relation between spectral shape, table length, and sine frequency is shown.
