In this paper we propose the use of a lattice based second order infinite impulse response (IIR) notch filter with a simplified adaptation algorithm for removal of power line frequency from ECG signals. The performance of this filter is better as compared to a second order infinite impulse response (IIR) notch filter for a real time ECG recording systems where the frequency of line varies over ...

In this paper, we thoroughly study a trilinear interpolation scheme previously proposed for the Body-Centered Cubic (BCC) lattice. We think that, up to now, this technique has not received the attention that it deserves. By a frequency-domain analysis we show that it can isotropically suppress those aliasing spectra that contribute most to the postaliasing effect. Furthermore, we present an eff...

In this paper arithmetic transformations for increased maximal sample rate of bit-parallel lattice wave digital filters implemented with carry-save arithmetic are proposed. The purpose is to increase the throughput in order to allow a reduction of the power consumption through supply voltage scaling. A lattice wave digital filter can be composed of firstand secondorder allpass sections which ar...

Combining intuitionistic fuzzy sets and filter theory,we studied interval valued intuitionistic (T, S)-fuzzy filters on lattice implication algebras. some relation properties of it are obtained, the relation between intuitionistic (T, S)-fuzzy filters and intuitionistic fuzzy set are discussed.The investigation method and content of lattice implication algebras are extended. Mathematics Subject...

In this paper, the concept of v-filters on lattice implication algebras is introduced by linking the Vague set and filter theory of lattice implication algebras; The properties and equivalent characterizations of v-filters are investigated; The relations between v-filters and filters are studied.

The well-known Richards’ Theorem of the continuous-time filter theory is reformulated in the digital domain in a convenient manner, leading to a simple derivation of cascaded lattice digital filter structures, realizing lossless bounded transfer functions. The theorem is also extended to the matrix case, leading to a derivation of m-input p-output cascaded lattice filter structures with lossles...

In this paper we propose an arithmetic transformation of firstorder allpass lattice wave digital filter sections implemented with bit-parallel, carry-save arithmetic which increases the maximum sample rate. Such filter sections are the critical component of bireciprocal lattice wave digital filters which are efficient filter structures for sample rate conversion with factors of two. The propose...

This paper discusses a method of regularity imposition onto biorthogonal linear-phase -band filterbanks using the lattice structure. A lifting structure is proposed for lattice matrix parameterization where regularity constraints can be imposed. The paper focuses on cases with analysis and synthesis filterbanks having up to two degrees of regularity. Necessary and sufficient conditions for regu...

Abstr(~ct-The definition of an N-D discrete time lossless bounded real (DTLBR) matrix and sufticient conditions on a state space representation to correspond to an N-D DTLBR matrix are given. Based on these suEcient conditions, it is shown that the transfer function of the n-D lattice filter, which is obtained fmm a stable 1-D lattice filter by replacing each delay element r *th z, (i = 1.2,. ....

We introduce the notion of n-fold implicative filters and n-fold implicative lattice implication algebras. We give characterizations of n-fold implicative filters and nfold implicative lattice implication algebras. Finally, we construct an extension property for n-fold implicative filter. 2000 Mathematics Subject Classification. 03G10, 06B10.
