Lowpass minimum phase filter design using IFIR filters

Gordana Jovanović Doleček, José Javier Díaz Carmona

Open publisher page 7 citations

Abstract

A design procedure for minimum-phase FIR filters using an interpolated FIR (IFIR) filter is proposed. The IFIR technique allows two linear-phase filters of much lower order to be designed and thereby making it easier to apply mipizing than is possible in high order FIR prototype filters. In this way, the problem of finding the roots of high order polynomials is overcome.
