On One-Multiplier Gray-Markel Lattice Allpass Structure
Bing Zeng, Yrjo A. Neuvo · 2005
One-multiplicr Gray-Markel lattice allpass structure is one of the minimal multiplier structures to realize an allpass filter. In this paper we study various fixed-point characteristics of the first-order and second-order one-multiplier Gray-Markel lattice allpass structures, including the scaling, roundoff noise and sensitivity properties, choice of sign parameters, limit cycle behavior, and application as building blocks in the parallel allpass realization of recursive filters.
