A unified approach to the design of optimum FIR linear-phase digital filters

James H. McClellan, T.W. Parks

Open publisher page 267 citations

Abstract

A method for designing finite-duration impulse-response (FIR) linear-phase digital filters is presented in which the four possible cases for such filters are treated in a unified approach. It is shown how to reduce each case to the proper form so that the Remez exchange algorithm can be used to compute the best approximation to the desired frequency response. The result is that a very flexible and fast technique is available for FIR linear-phase filter design.
