| Abstract: | This paper discusses the design of FIR filters that approximates a desired complex-valued frequency respome in the complex Chebyshev sense. An improved algorithm solving the dual of semi-infinite linear programming is presented.The algroithrn is a variant of the simplex method.It exhibits good convergence speed and numerical robust, Examples are presented to illustrate the performance of the algorithm. |
