Abstract:
|
We examine the problem of approximating a complex frequency response by a real-valued FIR filter according to the L<sub>2</sub> norm subject to additional inequality constraints for the complex error function. Starting with the Kuhn-Tucker optimality conditions which specialize to a system of nonlinear equations we deduce an iterative algorithm. These equations are solved by Newton's method in every iteration step. The algorithm allows arbitrary tradeoffs between an L<sub>2</sub> and an L<sub>oo</sub> design. The L<sub>2</sub> and the L<sub>oo</sub> solution result as special cases. |
