The disclosure relates to a method for determining the envelope curve of a modulated input signal with the following method steps: generating digital samples by digital sampling of the input signal, generating Fourier-transformed samples by Fourier transforming the digital samples, generating sideband-cleaned, Fourier-transformed samples (B'<SUB>n</SUB>) by removing a range with negative frequencies or a range with positive frequencies from the Fourier-transformed samples (B<SUB>n</SUB>), generating inverse-transformed samples by inverse Fourier transforming the sideband-cleaned, Fourier-transformed samples and forming the absolute value of the inverse-transformed samples.
