Abstract: A delta-sigma modulator (10) comprises a modulator loop (11) and a code generator (12). The modulator loop (11) comprises a loop filter (18). The code generator (12) is configured to generate a generator signal (BS) that is realized as an extended Barker code. The code generator (12) comprises a generator output (23) that is coupled to the loop filter (18).
