Abstract :
Investigates the design of lattice wave digital filters with arbitrarily specified magnitude and phase (or delay) characteristics. Design techniques focus upon the use of optimization through a quasi-Newton algorithm and an Lp-norm, to generate filter coefficients. Results are given to illustrate these design techniques and show how an increased group delay tolerance specification effects the overall filter order
