Abstract

This paper introduces algorithm for the design of FIR filter. This algorithm simultaneously minimizes the error present in the magnitude and group delay. This method is used to generate non-inferior solution under interactive environment. To generate the non-inferior solution, weighing method is used in which multiobjective optimization is converted into scalar optimization problem. The scalar is solved with the help of Hooke-Jeeves method. The use of optimization in filter designing allows the filter design with multi error criteria for both the pass band and stop band.

Keywords
