摘要

ina digital h & all; rhilfeger & auml; t, whoseausgangsverst & auml; rkera sigma delta modulator (4) is the ausgangswandler(7) including a high power consumption when no acousticaloutput wahrnehmbares output signal is generated. it istherefore proposed the following the sigma delta modulationa linear digital filtering, complete and professional; parties, so that the number ofhigh frequency flanks in typically pulsdichtemodulierten reduced output signal.
