| 摘要 |
<p>The present invention relates to a method and a system for generating an analog signal x(t) based on samples x[k] representing said analog signal, said method comprising the step of feeding said samples x[k] into a delta-sigma modulator (552 689), said delta-sigma modulator (552; 689) outputting a sequence of bits q[k], said method being characterized by the step of a non-linear time-discrete function into a feedback loop between a quantizer element (509; 691) and a delta element (506; 606) of said delta-sigma modulator (552; 689), wherein arguments of said non-linear time-discrete function comprise a current bit and at least one bit previous to said current bit.</p> |
