Design of FIR filters for low implementation complexity

Çiloğlu, Tolga
The minimisation of the total number of power-of-two terms is considered. The number of terms per coefficient is not constrained. Arbitrary phase filters are also designed where a method is introduced for the optimal utilisation of the filter gain. The method produces much better results than other methods in the literature with low computational requirements.


Analysis of root displacement interpolation method for tunable allpass fractional-delay filters
Hacıhabiboğlu, Hüseyin; Günel Kılıç, Banu (2007-10-01)
One of the simplest ways of designing allpass fractional-delay filters with maximally fiat group delays is by using the Thiran approximation by which the filter coefficients are calculated using a closed-form equation. However, due to the number of multiplications and divisions involved, the calculation of these coefficients is a computationally costly task and is not suitable for real-time applications. The analysis of a root-displacement-based interpolation method used in allpass tunable fractional delays...
Regular Remeshing of 3D Human Face Models
Yirci, Murat; Ulusoy, İlkay (2009-04-11)
Three dimesional polygonal models can be classified into three groups as irregular, semi-regular and regular. Regular models have advantages over the semi-regular and irregular ones in terms of efficient processing, memory requirements and rendering. Although most of the polygonal mesh generating methods yield irregular models, these models can be remeshed regularly. fit this paper, regular remeshing of three dimensional human face models are studied. These models are commonly used in computer graphics and ...
Design of Microstrip Quadruplet Filters on Filpro
Oruc, Sacid; Yıldırım, Nevzat (2018-11-02)
In this paper, a simple dimensional design procedure is developed for microstrip/stripline quadruplet filters by starting with direct BP synthesis of a lumped quadruplet with inverter couplings, K14, K12, K23 and K34. K14 is the cross-coupling inverter which creates a symmetric pair of finite transmission zeros (FTZ's) if the sign of K14 is opposite of the other inverters while a complex TZ is created if K14 has the same sign as the other inverters leading to linear phase (flat delay) responses. The LC reso...
Performance enhancement and comparison of discrete time current regulators for parallel active filters
Ozkaya, Hasan; Senturk, Osman Selcuk; Hava, Ahmet Masum (2007-09-05)
Discrete time linear and hysteresis current regulators (CR) for three-phase parallel active filters (PAF) are reviewed and evaluated. A novel discrete time hysteresis current regulation method with current oversampling and flexible PWM release capability, DHCR3, which has superior overall performance and simple implementation (no additional hardware) is proposed. Switching ripple filters (SRF) suitable for each CR type are designed. A DSP controlled PAF is designed and built for a three-phase 10 kW diode re...
Enhancing electrochromic properties of conducting polymers via copolymerization: Copolymer of 1-(4-fluorophenyl)-2,5-di(thiophen-2-yi)-1H-pyrrole with 3,4-ethylene dioxythiophene
Turkarslan, Ozlem; Ak, Metin; Tanyeli, Cihangir; Akhmedov, Idris M.; Toppare, Levent Kamil (2007-10-01)
A copolymer of 1-(4-fluorophenyl)-2,5-di(thiophel.1-2-yl)-1H-pyrrole (FPTP) with 3,4-ethylene dioxythiophene (EDOT) was electrochemically synthesized and characterized. While poly(FPTP) (P(FPTP)) has only two colors in its oxidized and neutral states (blue and yellow), its copolymer with EDOT has five different colors (purple, red, light gray, green, and blue). Electrochromic devices based on P(FPTP-co-EDOT) and poly(3,4-ethylenedioxythiophene) (PEDOT) were constructed and characterized. The oxidized state ...
