FSRFT - Fast simplified real frequency technique via selective target data approach for broadband double matching
This brief introduces a broadband double-matching (DM) solver called fast simplified real frequency technique (FSRFT). FSRFT is essentially a greatly accelerated variant of the well-known classical simplified real frequency ...
Dual band filter design using real frequency technique and frequency transformation
(Istanbul Univ, Fac Engineering, Elektrik-Elektronik Muhendisligi Bolumu, 2017)
In this work, we present a frequency transformation based dual-band filter design approach using scattering based real frequency technique. In the design process, conventional low-pass to band-pass frequency transformation ...
Dual band stop filter design via frequency transformation and synthesis with lumped resonators
(Institution of Engineering and Technology, 2020-05-01)
This study presents a new compact design technique for dual band stop (DBS) filter. Analytical formulation of DBS frequency transformation/mapping is derived in terms of parametric representation of band characteristic of ...
A design technique of 50 Ω terminated bandpass matching network and its implementation to a Y-shaped monopole antenna matching
In this paper, a 50 a"broken vertical bar terminated or in other words transformerless bandpass matching network design methodology and an implementation example are presented. The real frequency techniques are powerful ...

Design of multiband matching ladders without mutual coupling using parametric representation of Brune functions
(John Wiley and Sons Inc, 2020-10-01)
In this study, a semianalytical method for the design of mutual coupling free multiband matching networks is introduced. A new parametric representation of Brune functions is used for the construction of multiband ladder ...
Predictive vector quantization of 3-D mesh geometry by representation of vertices in local coordinate systems
(Elsevier Inc, 2007)
In predictive 3-D mesh geometry coding, the position of each vertex is predicted from the previously coded neighboring vertices and the resultant prediction error vectors are coded. In this work, the prediction error vectors ...
Digital color halftoning
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)
Digital color halftoning is done to create the perception of a continuous-tone color image using the limited spatiochromatic discrimination capability of the human visual system. Several techniques to perform this task are ...
An analog integrated circuit beamformer for high-frequency medical ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2012-10)
We designed and fabricated a dynamic receive beamformer integrated circuit (IC) in 0.35-mu m CMOS technology. This beamformer IC is suitable for integration with an annular array transducer for high-frequency (30-50 MHz) ...
Integration of 2D CMUT arrays with front-end electronics for volumetric ultrasound imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2008-02)
For three-dimensional (3D) ultrasound imaging, connecting elements of a two-dimensional (2D) transducer array to the imaging system's front-end electronics is a challenge because of the large number of array elements and ...
