摘要：
A device for pretreating a signal to be transmitted over a transmission path, wherein the transmission path comprises a band-pass filter whose pass-band width is smaller than a predetermined bandwidth and a non-linear amplifier, includes a linearization means for performing a linearization of the signal to be transmitted before the transmission of the same, such that a non-linearity caused by the non-linear amplifier is counteracted. Further, the device includes a signal-shaping means downstream to the linearization means comprising a frequency response such that the overall frequency response of the signal-shaping means and the band-pass filter corresponds to the frequency response of a filter whose pass-band width is at least equal to the predetermined bandwidth.
