Abstract: In a device for offering information, a network allows a connection to be set up between a display device with an operating unit and at least one data store, the offerable information being capable of being transmitted from the data store to and displayed at the display device with the operating unit in the form of different information types respectively designated by different symbols. At least one information type has a evaluation allocated to it and its corresponding symbol has a discriminator allocated to it that indicates the evaluation that is allocated to the corresponding information type.

Abstract: An amplifier is disclosed for electrical signals which consists of a plurality of series-connected amplification stages each of which has at least one voltage-controlled amplifier element whose control characteristic can be adjusted by means of a control signal. An amplification is desirable for all individual stages which is equally great over an arbitrarily preselectable dynamic range. According to the invention, the amplifier has at least one control signal forming element for each of the amplifier elements of each amplification stage which exhibit different control characteristics compared to one another. This control signal forming element forms a secondary control voltage U.sub.ST2 from a primary control voltage U.sub.ST1 according to the equation U.sub.ST2 =m.multidot.U.sub.
