Abstract

In a method of generating a correction function for an elimination of phase and amplitude errors of a compressed signal a reference function (hi(t)) is generated in accordance with patent application P 41 17 849.1-35 and a reference function (hf(t)) is generated by the optimum filter theory. Furthermore, the reference functions (hi(t) and hf(t)) of the ideal filter or optimum filter are fourier-transformed; the reciprocal value (1/Hf) of the one fourier-transformed signal (Hf) is multiplied by the other fourier-transformed signal (Hi), and the signal (Hi/Hf) obtained by the multiplication is subjected to an inverse fourier transformation for generating a correction function (hcorr(t)) in the time domain.
