Abstract:
A specific processing of information signals that is separate according to modulation portions and carrier portions is made possible by an arrangement for processing an information signal (14). The arrangement comprises a device (20) for converting the information signal (14) into a time/spectral representation by a block-by-block transformation of the information signal, and comprises a device (22) for converting the information signal of the time/spectral representation into a spectral/modulation spectral representation. This device (22) for converting is designed in such a manner that the spectral/modulation spectral representation is dependent on both an amount portion as well as on a phase portion of the time/spectral representation of the information signal (14). A device (24, 40) then carries out a manipulation or modification of the information signal (14) in the spectral/modulation spectral representation in order to obtain a modified spectral/modulation spectral representation. Another device (26) forms, in the end, a processed information signal (18) that represents a processed version of the information signal (14) based on the modified spectral/modulation spectral representation.
