Verfahren und Vorrichtung zum Erzeugen eines Ausgangssignals mit reduzierter Aussenbandabstrahlung

DE1005026927 A UPAB: 20060714 NOVELTY - The method involves producing an output signal (160) based on a complex, modulated input signal (102) which is divided into an amplitude signal (104) and a phase signal (106), which provide an amplitude signal path and a phase signal path (130). DETAILED DESCRIPTION - A first group running time distortion is brought about in the signal path which is counteracted by introducing a second group running time distortion by a second filter in the amplitude signal path (120) or phase signal path (30). The output signal (160) based on the signals is produced on an outlet of the amplitude signal path and on an outlet of the phase signal path. An analog-digital transformation is provided before or after a transformation of the complex modulated signal of the amplitude signal and phase signal. An INDEPENDENT CLAIM is included for a device. USE - For communication system ADVANTAGE - Provides reduced outer band radiatio
