Custom designed high-order frequency transformations for IIR filters
This paper addresses high-order frequency transformation and extends standard Constantinides, Mullis/Franchitti transformations and the exact N-point approach we have previously reported. Using specially designed M/sup th/ order allpass filters, mapping of N features of the prototype filter can be carried out independently (where N
