摘要：

A synthesis methodology for selecting locations of the z-domain poles for noise-shaping coders that use multibit internal converters is presented. A key aspect of the proposed methodology is the use of the Absolute value of L1 norm of the noise transfer function to guarantee stability rather than the power gain or Absolute value of L2 norm which is commonly used in the design of 1-bit noise-shaping coders. Simulation verifies that the performance predicted by the new method is within a few dBs of the actual performance. In addition, two hand-designed loop filters from the literature are compared with designs generated by the proposed method.
