Frequency Selective KYP Lemma And Its Applications To IIR Filter Bank Design

Abstract

For a transfer function/filter F(e(Jw)) of order n, Kalman-Yakubovich-Popov (KYP) lemma characterizes the intractable semi-infinite programming (SIP) condition F(e(-Jw)) 1 Theta [F(e(-Jw)) 1]>= 0 for all omega in frequency domain by a tractable semi-defi
