Abstract

In this paper, we consider the implementation of the prototype filter of biorthogonal cosine-modulated filter banks on processors with fixed-point arithmetic. The realization is based on zero-delay and maximum-delay matrices. We show that the perfect reconstruction property of the filter bank is not affected by quantization, rounding and overflow. We also demonstrate how the latter operations influence the frequency selectivity of the filter bank.
