Abstract
A method and apparatus for analyzing a signal, in which a spectrum of the signal is provided, which spectrum is the result of a multiplication of the signal by a predefined window function and a subsequent Fourier transform, the highest spectral line and the adjacent second-highest spectral line are determined in the spectrum in the region of at least one local maximum, the amplitude of the highest spectral line and of the second-highest spectral line is determined, at least one value dependent on the amplitude of the highest spectral line and on the amplitude of the second-highest spectral line is determined, a frequency correction value is determined for the frequency of the highest spectral line from the determined value using a frequency correction characteristic curve which was created for the predefined window function, and the frequency of the highest spectral line is corrected by the frequency correction value.
