Finite wordlength design of wave digital filters
Ahmad R. Mirzai, S.S. Lawson · Electronics Letters · 1986
The letter illustrates some examples from a software package for the design of finite wordlength wave digital filters (WDFs). Given a set of initial coefficients, the program generates a new set of coefficients which are quantised to the required number of bits. Some filter design examples have been considered to illustrate this for three types of WDF, i.e. unit element, lattice and LC-ladder WDFs.
