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 () for the production of the signals with a certain signal form and signal adjustment means () for the adaptation or pre-distortion of the signals. The signal generation means () according to the invention are digitally realized, by using a programmable shift register (), which contains multipliers specified by the standard signal form for multiplication with a digital input signal (). The signal adjustment means () comprise substantially scalable digital filter arrangements in the form of a serial connection of digital filters () with a downstream multiplexer (). Moreover, the invention provides attenuating means () for attenuation of the signal dependent on the characteristics of the telecommunication channel.
