Maximally fast scheduling of bit-serial lattice wave digital filters using constrained third-order sections
Oscar Gustafsson, Lars Wanhammar · 2003
Recently a novel method to increase the sample rate for lattice wave digital filters (WDFs) has been proposed. It shows that it will lead to approximately doubling the maximal sample rate. In this paper we show how to achieve the maximal sample rate using cyclic scheduling. Bit-serial arithmetic is assumed, but the same ideas hold true for digit-serial and bit-parallel arithmetic as well.
