Paper Abstract

In this paper we present an method for designing 2-D linear phase FIR diamond subband filters having the perfect reconstruction property. It is based on a transformation of variable technique and is equivalent to the generalized McClellan transformation. We present methods to design a whole class of transformations. The method provides the flexibility of controlling the frequency characteristics of the filters with ease. With this method the problem consists of two parts: design of the transformation and design of the 1-D filters. The filters designed with this method can be implemented efficiently by employing separable processing along the diagonal directions. Several numerical design examples are presented to illustrate the flexibility of the design method.
