In this paper, we present the design optimization of oneand two-dimensional fully-pipelined computing structures for areadelay-power-efficient implementation of finite impulse response (FIR) filter by systolic decomposition of distributed arithmetic (DA)based inner-product computation. The systolic decomposition scheme is found to offer a flexible choice of the address length of the look-up-tab...

This paper considers adjustable fractional delay FIR filters and their design. We employ a filter structure that in [1] is referred to as the modified Farrow structure. This structure makes use of a number of linearphase FIR subfilters. In [1], all subfilters are of odd and equal order. In this paper, we consider the case where the subfilters in general have different orders, which results in a...

The finite impulse response filters are inherently stable and have linear phase response property. The main drawback of these filters is lies in requirement of higher orders for similar magnitude response compared to Infinite Impulse response filters. Also the amount of computational complexity needed for the implementation of the filter, especially for the filters with narrow transition band i...

In this paper we study certain types of positive fuzzy quasi-orders on semigroups and their links with completely semiprime ideals, prime filters. We characterize various properties a quasi-order Q in terms the its left right eigen spaces IQ CQ, solution sets set equations corresponding to Q. also demonstrate applications obtained results semilattice decompositions semigroups. The shed new ligh...

This paper presents a new approach based on the use of Current Steering (CS) technique for design fully integrated Gm–C Low Pass Filters (LPF) with sub-Hz to kHz tunable cut-off frequencies and an enhanced power-area-dynamic range trade-off. The proposed has been experimentally validated by two different first-order single-ended LPFs designed in 0.18 µm CMOS technology powered 1.0 V single supp...

This paper discusses the use of nonlinear filters that are based on linear digital filters with input-signal-dependent coefficients in the context of digital waveguide synthesis models. It is proposed that the practical uses of such filters in music synthesis may be generalized to a time-varying fractional delay (TVFD) filter with signal-dependent coefficients. Three different cases are outline...

Technologies have advanced rapidly in the field of digital signal processing due to advances made in high speed, low cost digital integrated chips. These technologies have further stimulated ever increasing use of signal representation in digital form for purposes of transmission, measurement, control and storage. Design of digital filters especially adaptive or semi adaptive is the necessity o...
