Abstract
The invention relates to a transmitter for transmission of digital data via a transmission line (10), comprising a current-driving digital/analogue converter (1) which is arranged at the input of the transmitter; a current-operated form filter (2) for forming the current pulses which are supplied from the digital/analogue converter; a line driver (5) which carries out current/voltage conversion; and a circuit for offset compensation (6), which is arranged in a feedback path (11). In order to improve the quality of the pulses which are transmitted at the output of the transmitter, the invention proposes that the internal signal processing of the transmitter be carried out on a current basis.
