ABSTRACT:
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′n) by removing a range with negative frequencies or a range with positive frequencies from the Fourier-transformed samples (Bn),generating inverse-transformed samples by inverse Fourier transforming the sideband-cleaned, Fourier-transformed samples andforming the absolute value of the inverse-transformed samples.
