Design of multirate filter banks by ℋ/sub ∞/ optimization
Tongwen Chen, Bruce Allen Francis · IEEE Transactions on Signal Processing · 1995
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 /spl Hscr//sub /spl infin// optimization, for which there is ready-made software.
