Résumé
Lattice Wave Digital Filters (LWDFs) are known to be insensitive to finite precision arithmetic effects and can readily be designed for standard filtering applications using a set of explicit formulas elaborated by Gazsi. <br> This paper presents the necessary elements to develop an LWDF design package within the Signal Processing Workstation (SPW) design framework. This package, based on Gazsi's formulas and additional frequency transformations, supports the realisation of lowpass, highpass, bandpass and band-reject filters using either Butterworth, Chebyshev, or Elliptic approximations. Ideal and finite precision arithmetic models of the basic LWDF components are also provided to perform detailed simulations.
