Optimal design of FIR filters with the complex Chebyshev error criteria

  title={Optimal design of FIR filters with the complex Chebyshev error criteria},
  author={Daniel Burnside and Thomas W. Parks},
  journal={IEEE Trans. Signal Processing},
We present an improved algorithm for an established filter design problem, the design of an FIR filter that best approximates, in the complex Chebyshev sense, a desired complex-valued frequency response. The algorithm is a variant of the simplex algorithm of linear programming, which has an interpretation as an implicit multiple exchange. It is iterative, robust, and exhibits good convergence speed. Global optimum convergence is guaranteed. Both complex and real-valued impulse responses can be… CONTINUE READING
