Abstract

Lattice structures have found an increasing number of applications in the signal-processing area during the past decade. These structures can be used as alternative forms to realize a given filter transfer function or to parametrize a signal model.¹ Compared to other realization forms, lattice structures have some advantageous characteristics, such as straightforwardness of implementation, modularity, regularity, and good sensitivity properties, which are very attractive for filtering applications.
