Techniques based on the frequency-response masking (FRM) approach are known to be highly effective for reducing the number of multipliers and adders in linear-phase finite-impulse response (FIR) filters. The basic FRM structure comprises a band-edge shaping filter and two masking filters. It is observed that the impulse response of the band-edge shaping filter of an FRM structure exhibits a qua...

chapter one is devotod to collect some notion and background informations, which are needed in the next chapters. it also contains some important statements which will be proved in a more general context later in this thesis. in chapter two, we show that if the marginal factor-group is of order np1...pk,n>1, then we obtain a bound for the order of the verbal subgroup. also a bound for the bear-...

Introduction: Leukocytes causing a wide variety of side effects after transfusion are present in all blood products prepared by standard methods. As a consequence, the use of filter technology for leukoreduction has been widely practiced .According to AABB accreditation in 1996, leukoreduced blood components must contain less than 5×106 leukocytes per unit, but sometimes this value is higher ev...

This paper presents a new mixed-mode (including voltage, current, transadmittance, and transimpedance modes) biquad filter using only two differential voltage current conveyors (DVCCs), two grounded capacitors and three grounded resistors, which are the least number of active components and the minimum number of grounded passive components necessary for realizing current-mode (with high output ...

The electrocardiogram (ECG) signal carries vital information related to cardiac activities. While measuring ECG using electrodes, the is contaminated with powerline interference (PLI) from harmonics, baseline wandering (BW), motion artefacts (MA) and high frequency (HF) noise. extraction of signal, without loss useful noisy environment, required. Therefore, selection implementation an efficient...

In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...
