An application of H/sub ∞/ optimization to multirate digital signal processing
T. Chen, Bruce Allen Francis · 2002
A procedure is developed to design IIR synthesis filters in a multirate filter bank. The filters minimize the l/sub 2/-induced norm of the error system between the multirate filter bank and a desired pure time-delay system. This criterion is reduced to one of H/sub /spl infin// optimization, for which there is ready-made software.
