ABSTRACT:
The invention describes a device for the low-distortion conversion, especially amplification, of signals. In one embodiment, the device comprises a digital-to-analog converter having adjustable reference voltages to which an analog-to-digital converter having adjustable reference voltages may be connected upstream. In a further embodiment, the device has a unit, which predistorts a digitized signal, or a digital signal, corresponding to the characteristic transfer line of the amplifier. In a further embodiment, the device has a unit, which equalizes a distorted digitized signal corresponding to the characteristic transfer line of the amplifier stored in the unit. In yet a further embodiment, the device has a digital-to-analog converter operating on the basis of the summation of weighted currents.
