On Group-Delay Sensitivity Properties of Complex Allpass Lattice Filters
Summary :
The group-delay sensitivity is studied theoretically for Gray and Markel allpass lattice filter realizing complex transfer function. Recursive expressions which were derived for phase and group-delay in real lattice are rederived for the complex case. These expressions are used to obtain upper bounds on group-delay sensitivity. The minimum number of frequencies where group-delay sensitivity becomes zero is discussed. Results corresponding real allpass lattice are also shown. Phase sensitivity properties of these filters are analyzed and compared with existing results. A new bound on phase sensitivity is also obtained.
