METHOD AND APPARATUS FOR LOW DELAY RECURSIVE FILTER DESIGN

摘要

A method and apparatus for low delay recursive filter design. The method includes determining a predefined filter template with higher magnitude specification than a target filter design, determining at least one relaxation bound on the filter specification utilizing the predefined filter template, specifying at least one constraint for the target filter design utilizing the at least one relaxation bound, and determining a low delay recursive filter design for minimizing the average group delay of the filter utilizing the at least one constraint.
