A new technique for rational digital filter design is presented which is based on results in complex function theory due to Takagi, Krein, and others. Starting from a truncated or windowed impulse response, the method computes the unique optimum rational Chebyshev approxittlation with a prescribed number of stable poles. Both phase and magnitude are matched… (More)
