Abstract
A digital/analog converter contains an input for supplying a first digital word having a first word length. A noise shaper is coupled to the input and is designed to convert the first digital word into a second digital word having a second word length and to output this digital word to an output. The output of the noise shaper has a filter device coupled to it which is designed to reject signal components in the second digital word. Finally, a conversion device is connected to the output of the filter device. The conversion device is designed to convert the second digital word into an analog signal and to provide the analog signal for an output. By filtering the signal which is output by the noise shaper, the noise components contained in the noise-shaped second digital word are rejected.
