摘要	The invention relates to a delta sigma D/A converter (48) by means of which a digitally valued input signal can be converted to a binary output signal that is time-discrete corresponding to one cycle. In the process, an analog representation of the value of the input signal can be produced using a mean value of the output signal, which has been formed over several cycles. The delta sigma D/A converter (48) is designed such that, during use, said converter provides the output signal by stringing together signal patterns of a set of signal patterns, wherein the signal patterns of the set are each binary, time-discrete corresponding to the cycle, and extend over a signal pattern cycle length of several cycles. At least two signal patterns of the set have signal pattern mean values which are different from each other, and which are formed over the respective signal pattern cycle length, and all the signal patterns of the set each have substantially the same number, in particular precisely the same number, of flanks.
