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.

Abstract: A method provides for the current address tables present in a respective subscriber equipment monitoring a ring-shaped network to be distributed to all subscriber equipment of the n ring-shaped networks connected therto. After the existence of the current address tables, distribution information are formed in the subscriber equipment monitoring the ring-shaped networks and are transmitted to the further subscriber equipment of the respective ring-shaped networks. When a subscriber equipment has access to a further ring-shaped network, this, in turn, forms a further distribution information and transmits the same to its appertaining ring-shaped network.
