Normalized peak rippple magnitude as an objective function in discrete coefficient fir filter design

Normalized peak ripple magnitude (NPRM) has been a convenient design criterion for discrete coefficient FIR filters. "Filter gain" is the major concern for NPRM. This paper presents an exact closed form expression of the filter gain for a given set of filter coefficients. Based on this expression the characteristics of NPRM cost function are discussed. The selection of the initial value of the filter gain for suboptimal design methods is considered. Deficiency of the previously proposed methods is pointed out and a way to overcome the problem is presented. Proposed solution provides additional information that has been proved to be useful in determining the initial point when using a suboptimal optimization method.


Fourth generation effects in rare exclusive B -> K*l(+)l(-) decay
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-10-02)
Influence of the fourth generation, if ever exists, on the experimentally measurable quantities such as invariant dilepton mass distribution, lepton forward-backward asymmetry, and the ratio Gamma(L)/Gamma(T) of the decay widths when K* meson is longitudinally and transversally polarized, is studied. Using the experimental results on the branching ratios for the B --> X(s)gamma and semileptonic B --> X(c)l (v) over bar decays, the two possible solutions of the 4 x 4 Cabibbo-Kobayashi-Maskawa factor Vt'sVt'b...

Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30)
The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.

Radiative Delta -> N gamma decay in light cone QCD
Alıyev, Tahmasıb; Savcı, Mustafa (1999-12-01)
The g(Delta N gamma) coupling for the Delta-->N gamma decay is calculated in the framework of the light cone QCD sum rules and is found to be g(Delta N gamma)=(1.6+/-0.2) GeV-1. Using this value of g(Delta N gamma) we estimate the branching ratio of the Delta(+)-->N gamma decay, which is in a very good agreement with the experimental result. [S0556-2821(99)02023-8].
Strong Coupling Constants of Negative Parity Heavy Baryons with pi and K Mesons
Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2017-01-01)
The strong coupling constants of negative parity heavy baryons belonging to sextet and antitriplet representations of SUf(3) with light pi and K mesons are estimated within the light cone QCD sum rules. It is observed that each class of the sextet-sextet, sextet-antitriplet, and antitriplet-antitriplet transitions can be described by only one corresponding function. The pollution arising from the positive to positive, positive to negative, and negative to positive parity baryons transitions is eliminated by...
