Abstract

A device for the production of standard compliant signals, for example pulse-type signals in a telecommunication network, serves the production and adaptation and/or pre-distortion of signals with a certain signal form, which is defined dependent on a standard signal form specified in a standard. The device comprises signal generation means (10) for the production of the signals with a certain signal form and signal adjustment means (20) for the adaptation or pre-distortion of the signals. The signal generation means (10) according to the invention are digitally realized, by using a programmable shift register (14), which contains multipliers specified by the standard signal form for multiplication with a digital input signal (1). The signal adjustment means (20) comprise substantially scalable digital filter arrangements in the form of a serial connection of digital filters (22) with a downstream multiplexer (24). Moreover, the invention provides attenuating means (50) for attenuation of the signal dependent on the characteristics of the telecommunication channel.
