Abstract: The present disclosure relates to a modulator for a digital amplifier and a device comprising such a modulator and a digital amplifier. The modulator includes a pulse shaper and a control unit for controlling the pulse shaper to convert an input signal into a bit stream configured for a digital amplifier which encodes an amplitude value per clock of a carrier signal. The pulse shaper can represent a respective amplitude value of the input signal with different bit patterns. The control unit includes an assignment of the control commands to associated amplitude values resulting from amplification of the associated bit patterns with the digital amplifier is stored or at least is provided in that the control unit selects a control command per clock by means of the assignment and the amplitude value of the input signal and drives the pulse shaper accordingly.

Abstract: The present invention relates to a modulator for a digital amplifier and a device comprising such a modulator and a digital amplifier. The modulator (100) comprises a pulse shaper (110) and a control unit (120) for controlling the pulse shaper (110) to convert an input signal into a bit stream (130) configured for a digital amplifier which encodes an amplitude value per clock of a carrier signal. The pulse shaper (110) can represent a respective amplitude value of the input signal with different bit patterns. The bit pattern respectively used by the pulse shaper is determined by the control unit (120) by means of a corresponding, associated control command.
