Abstract

An analog-digital processing unit including an amplifier with amplification that is adjustable in stages, and a quantizer outlet connected downstream of the amplifier. The output of the quantizer acts as actual value to control the amplification of the amplifier. With the assistance of the instantaneous value output from the quantizer, and the instantaneous prevailing amplification, the signal values, compensated by the instantaneous amplification, are defined and are output in a memory and scaling unit.
