Abstract

The invention relates to a signal processing unit for a signal processing path (1) for altering a first property of a received signal (s1), comprising an output module (2, 3) for the output of the signal (s2), altered in the signal processing path (s1), as output signal (s3), whereby the signal processing path (1) carries out a change to a second property of the received signal (s1) according to a first transmission function and whereby the output module (2, 3) comprises an adjustable amplifier (2), arranged downline of the signal processing path (1), to which the altered signal (s2) is supplied and which amplifies the same according to a second transmission function relating to the second signal property and provides the same as an output signal (s3) and an adjuster module (3) which adjusts the second transmission function of the amplifier as the inverse of the first transmission function.
