05 Sep 1989TL;DR: In this paper, the authors investigated the design of digital filters with arbitrarily specified magnitude and phase characteristics, focusing on the preservation of filter structure and the use of optimization to find a suitable set of multiplier coefficient values.
Abstract: Investigates the design of digital filters, with arbitrarily specified magnitude and phase (or delay) characteristics. We shall be looking in particular at Wave Digital Filters because of their known superior performance in respect of round-off noise and coefficient quantization error. The emphasis in this paper is the preservation of filter structure and the use of optimization to find a suitable set of multiplier coefficient values. Results are given to illustrate the current progress in this research. >

TL;DR: In this paper, the design of lattice wave digital filters with arbitrarily specified magnitude and phase (or delay) characteristics has been investigated, focusing upon the use of optimization through a quasi-Newton algorithm and an Lp-norm, to generate filter coefficients.
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. >

TL;DR: In this paper, a filter structure is considered which is made up from all-pass sections, and two design approaches are examined using classical optimization and simulated annealing, and design examples are provided which illustrate the efficacy of these techniques.
Abstract: For high sampling rate applications it is useful if the digital filter structure is efficient in the sense of a minimum number of arithmetic operations for a given order. In addition, requirements for satisfying the stringent magnitude and delay specifications lead to the choice of non-minimum phase transfer functions. To this end, a filter structure is considered which is made up from all-pass sections. Two design approaches are examined using classical optimization and simulated annealing. Design examples are provided which illustrate the efficacy of these techniques. >
