Designing IIR digital all-pass filters by successive projections method
The transfer function of IIR all-pass filters is a rational function of omega. However, the optimization of such a rational function using the successive projections method, which has a wider range of application than the Remez algorithm, has not been presented. In this paper, we propose designing IIR allpass filters using the successive projections method.
