TRANSMITTER FOR TRANSMITTING DIGITAL DATA OVER A TRANSMISSION LINE

摘要

The invention relates to a transmitter for transmitting digital data over a transmission line (10). Said transmitter comprises a current-generating digital/analog converter (1) connected to the input of the transmitter, a current-controlled shaping filter (2) for shaping the current pulses delivered by the digital-analog converter, a line driver (5) which carries out a current-voltage conversion and an offset compensation circuit (6) arranged in a feedback path (11). In order to improve the quality of the pulses transmitted to the output of the transmitter, the internal signal processing in the transmitter is carried out based on current.
