Abstract – A voltage-mode (VM), multi-input single-output (MISO) type multifunction biquad is proposed. It uses only one operational transresistance amplifier (OTRA) as the active element, while previously reported VM multifunction filters require more OTRAs. Proposed MISO type biquad configuration can realize all five different filter transfer functions. Theoretical results are verified with P...

In this paper, a circuit employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs) as active element is proposed which can function both as biquad filter and oscillator. It uses two CCCCTAs and two capacitors. As a biquad filter it can realizes all the standard filtering functions (low pass, band pass, high pass, band reject and all pass) in voltage-mode and provides ...

This paper presents a tunable bandstop filter design using defected ground structure (DGS) where FR4 substrate is used as a low cost solution compared to others substrate such as Teflon and Rogers RT/Duroid. Thus, the performance of the tunable DGS bandstop filter using FR4 substrate is analyzed in this paper. Besides, analytical modeling of the tunable bandstop filter is derived and discussed ...

The use of a volume holographic filter as collector element in a confocal system imaging through scattering (turbid) material is described. We show that the penetration depth of the volume holographic system is de-coupled from the scatter noise discrimination properties, and is potentially more advantageous than the traditional confocal microscope. Since the volume-holographic filter is a match...

Explicit filtering has the effect of reducing numerical or aliasing errors near the grid scale in large eddy simulation (LES). We use a differential filter, namely the inverse Helmholtz operator, which is readily applied to unstructured meshes. The filter is invertible, which allows the sub-filter scale (SFS) stresses to be exactly reconstructed in terms of the filtered solution. Unlike eddy vi...

A lifting based 2D DWT with efficient folded architecture and parallel scanning is being proposed. The architecture results in lesser hardware complexity and memory requirement due to multiplexing of 2 stages of lifting architecture. The 2D DWT architecture is realized by cascading two 2D processing elements. The coefficients for the lifting stage were chosen according with 9/7 filter. The 1D p...

This article presents an efficient ad hoc multicast communication protocol for next-generation cyber-physical systems and computational materials. Communication with such systems would be gestural, and when cells within such materials detect a motion, they would share that information with each other. We want to achieve efficient communication among only the group of nodes that sense a particul...

In this paper we will present a series of experiments comparing the correlation characteristics of two nonlinear data smoothing methods. Firstly the Recursive Median sieve, a multiscale dataanalysis system, implemented as a cascade of Recursive Median (RM) filters of increasing window lengths. Secondly a plain RM filter, applied directly to the original input signal. The point that we want to m...

Abs&act-A linearity improvement technique employing passive resistors and current-steering MOS transistors as a variable resistance element is proposed to implement a low-distortion filter in CMOS technology. This proposed implementation relies on the linearity of the passive resistors and the tunability of the current-steering MOS transistors operating in the triode region to overcome the limi...

Bloom filters provide a spaceand time-efficient mean to check the inclusion of an element in a set. In some applications it is beneficial, if the set represented by the Bloom filter is only revealed to authorized parties. Particularly, operations data in supply chain management can be very sensitive and Bloom filters can be applied to supply chain integrity validation. Despite the protection of...
