Method for reducing computational errors in a useful band of a signal generated with a fourier transform, for fixed-point microprocessors

摘要

A method for reducing computational errors in a useful band of a signal generated with a Fourier transform, particularly for fixed-point microprocessors, which comprises a step of shifting errors present in a signal due to Fourier transforms applied thereto, so that the errors straddle a frequency in which the information content of the signal is irrelevant.
