摘要： In the line terminating device, which is provided for transmitting and receiving narrowband low-frequency voice signals and broadband data signals at a higher frequency, the analog reception path is subdivided into two separate analog paths (32, 33) for voice and data using a balance filter (49), which is used for data signal echo cancellation. In the transmission direction, the voice signal path and the data signal path are separated in the digital part by means of digital filters (43, 45). The invention is used for voice and data signal separation in xDSL methods, for example, ADSL.Lite.

摘要： An analog-digital converter includes a differential amplifier having collector resistances each being in the form of a resistance line. Node points between resistance segments of the resistance lines are in the form of output terminals. Comparators with a balanced input are provided in the same amount as the resistance segments. In each case one input of a comparator is connected to an output terminal of a first resistance line and another input of the comparator is connected to an output terminal of a second resistance line. Therefore, the same resistance value in each case acts between two output terminals, which are connected to one comparator, in the collector circuit of the differential amplifier.

摘要： A coding circuit forming a 1-from-N code from an X-from-N code includes partial circuits in which each position of the X-from-N code forms an input value of a partial circuit. Each partial circuit is formed of three emitter-coupled transistor pairs, a current source connected to reference potential, level shift circuits, signal outputs and a symmetrical signal input. Each partial circuit is connected to the partial circuit with the next higher position of the X-from-N code as an input value and to the partial circuit with the next lower position of the X-from-N code as an input value.
