18 ABSTRACT: In a circuit for amplifying and/or attenuating a signal, which circuit comprises an amplifier stage having an inverting input and a non-inverting input and an output, a first voltage divider having n taps is arranged between an input terminal and ultimately a point of constant potential. The taps are connected to a first controllable switching unit for switching individual ones of the taps to the non- inverting input of the amplifier stage. Further, a second voltage divider having m taps is connected between an output terminal, which is the output of the amplifier stage, and (ultimately) the point of constant potential. The tape of the second voltage divider are connected to a second con- trollable switching unit for switching individual ones of these taps to the inverting input of the amplifier stage.
