Fuzzy Logic (FL) based algorithms have emerged as one of the most interesting areas for many applications. The high growth of fuzzy logic applications led to the need of finding efficient way for its hardware implementation. Therefore, the implementation of a FL through the use of the Very high speed integrated circuits Hardware Description Language (VHDL) code is also becoming popular. In this paper,...
In this paper, the root-cause for the appearance of various noises in the image and video are described. A hardware implementation of the median filter using Dynamic Partial Reconfiguration (DPR) technique to restore grayscale and color image having salt & peppers and random-valued impulse noise is proposed. The performance of proposed pipelined-parallel DPR architecture is validated in terms...
In this paper a novel asymmetric CPW fed with conjoined S-shape antenna presented for multiband applications. The antenna is designed on the Taconic RF-35 dielectric substrate of 20 mm (width) × 18 mm (length) × 0.76 mm (thickness) with relative permittivity 3.5. In order to generate multi band characteristics, the parallel slots are placed above the radiating patch, additional resonances are excited...
A compact size staircase planar antenna using composite metamaterial with coplanar waveguide fed is presented. The staircase ground is etched from the FR4 epoxy substrate with the thickness of 1.6mm. The proposed antenna is of size 27 × 31.7 mm2. The negative index metamaterial consisting of SRR and CRR with staircase ground is employed to design this antenna. A pair of slot is introduced on the staircase...
A multisleeve slot monopole antenna with coplanar waveguide fed is proposed for radio frequency identification (RFID) tag applications. The designed antenna with the size of 12 × 13 mm2 including the FR‐4 substrate can operate at 5.8 GHz with the gain of 3.45 dBi in the measured bandwidth of 11.38%. Broadside and bidirectional E‐plane and almost omnidirectional H‐plane radiation patterns are observed...
A low-noise amplifier (LNA) with high gain is presented. The LNA is the outer most part of a transceiver and it is responsible for providing enough gain to the signal with the least distortion possible. This system uses current-reuse technique to achieve high gain with minimal noise. The CMOS 0.18μm technology has been chosen for the design of the LNA at the transistor level. Agilent's ADS tool has...
The interdependency between pitch estimation and pitch-based separation creates a problem for pitch estimation and voice separation. It is observed that the target pitch can be estimated from a few harmonics of the target signal. The trend estimation algorithm is proposed to bound the singing pitch in a plausible range and an extended tandem algorithm is also proposed that estimates target pitch and...
Artificial Neural Networks (ANNs) have been used as a promising tools for many applications. In recent years, a computer-aided design approach based on ANNs has been introduced to microwave modeling, simulation and optimization. In this work, the characteristics parameters of the conductor-backed asymmetric coplanar waveguide (CB - ACPW) with one lateral ground plane have been determined with the...

In this paper, a new conformal mapping quasi static approximation method based on ANNs is used to calculate accurately the odd-and even-mode characteristic impedances, coupling coefficient and effective permittivities of CB-ECCPWs. ANNs have been recently recognized as a fast and flexible tool for RF and microwave modeling, analysis and design. ANN models are developed from measured or simulated microwave...
