Abstract
This correspondence explains the reason for obtaining negative estimates for power density spectra in numerical calculations. The major source of error is not what is ordinarily believed a precision problem [1] in the computer program. The main error lies in using the usual Fourier cosine transform definition which is no longer valid for numerical work. A more appropriate definition is suggested.
