Some compact generalization of inequalities for polynomials with prescribed zeros
Let $p(z)=z^s h(z)$ where $h(z)$ is a polynomial of degree at most $n-s$ having all its zeros in $|z|geq k$ or in $|z|leq k$. In this paper we obtain some new results about the dependence of $|p(Rz)|$ on $|p(rz)| $ for $r^2leq rRleq k^2$, $k^2 leq rRleq R^2$ and for $Rleq r leq k$. Our results refine and generalize certain well-known polynomial inequalities.
متن کاملDesign and Implementation of Compact Hy- Brid Four-mode Bandpass Filter with Multi- Transmission Zeros
Abstract—This paper presents a novel compact microstrip hybrid four-mode bandpass filter (BPF) with good selectivity and multitransmission zeros. By adding an external resonator to a triplemode stub-loaded resonator, four modes are generated in the desired passband and a hybrid four-mode BPF is implemented. Oddand even-mode theory is introduced to investigate the mode characteristics of triple-...

متن کاملWaffle Procedure for Selected Patients with Constrictive Pericarditis
Pericardiectomy is the standard procedure used to relieve hemodynamic conditions produced by constrictive pericarditis (CP), a form of severe diastolic heart failure. CP is observed in 0.2%– 0.4% of patients undergoing cardiac surgery. They generally have experienced pericardial trauma or inflammation [1]. Despite its poor prognosis when untreated, CP is potentially curable. Surgical pericardie...
متن کاملDesign of conjugate quadrature filters having specified zeros
Conjugate quadrature lters with multiple zeros at 1 have classical applications to unitary subband coding of signals using exact reconstruction lter banks. Recent work shows how to construct, given a set of n negative numbers, a CQF whose degree does not exceed 2n-1 and whose zeros contain the speci ed negative numbers, and applies such lters to interpolatory subdivision and to wavelet construc...
