Optimum Discrete Coefficient Realization of FIR Filters

Speaker: Dr Wei-Yong Yan, Curtin University of Technology

When: 03.15PM, Wednesday 05 Feb 2003

Venue: 78-420

Host: Associate Professor Brian Lovell

Abstract:

   Most existing FIR filter design methods are based on infinite
   precision arithmetic and thus lead to filters which cannot be
   readily implemented with microprocessors. Such infinite precision
   filters have to be transformed into finite precision filters using
   techniques such as coefficient quantization and rounding before
   they can be implemented with hardware.  Among finite precision
   filters, FIR filters whose coefficients are restricted to a sum of
   signed powers of two are particularly attractive as they can be
   implemented without using any multipliers, which often greatly
   contribute to the cost and complexity. In this seminar, the problem
   of optimal approximation of a given FIR filter by a filter with
   discrete coefficients will be discussed. An analytic approach to
   the problem will be described.
