| Abstract: | It is shown how erroneous results can occur using some period-finding methods, such as Fourier analysis, on data containing closely spaced frequencies. The frequency spacing accurately resolvable with data of lengthT is increased from the standard value of about 1/T quoted in the literature to approximately 1.5/T. |
