Abstract
A converter has a ladder network of resistor means for converting binary words to amplitude values according to an expansion curve. One of the transverse resistor means of the ladder network comprises a resistor chain, each terminal of which is connected through one of a set of first switches to the output of the converter. Each of the nodes of the ladder network is connected through one of a set of second switches to one reference voltage. The first and second switches are activated in response to interval- and segment-identity signals, respectively. Each conversion is carried out by generating an actual combination comprising one interval- and one segment-identity signal, and, consequently, by switching one of the first and one of the second switches.
