چکیده
Seueral techniquesare available for implementingascalardigitaffilter using lattice and ladder structures which are known to yield low noise realizations. Ofthese, the lattice and ladder structures proposed by Gray and Markel have the advantage of being interimlly scaled Block implementation of a scalar digitalfilteroflers a number of advantages. Inthis pnpet, new algorithms to realize block digitalfiltersin the form of cascaded lattice or ladder hvo-pairs are proposed. Block larrice and ladder structures similar to Gray an@ Markers scalar structure are obtained b j using Lrvinson recursion Also, normalized block lattice and ladder structures are developed.

Discrete Version of Richard’s Theorem and Applications to Cascaded Lattice Realization of Digital Filter Transfer Matrices and Functions
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...
متن کاملNumerical analysis of gas flows in a microchannel using the Cascaded Lattice Boltzmann Method with varying Bosanquet parameter
Abstract. In this paper, a Cascaded Lattice Boltzmann Method with second order slip boundary conditions is developed to study gas flows in a microchannel in the slip and transition flow regimes with a wide range of Knudsen numbers. For the first time the effect of wall confinement is considered on the effective mean free path of the gas molecules using a function with nonconstant Bosanquet para...
متن کاملQuantization noise analysis of wave digital and lossless digital integrator allpass/lattice filters
Quantization noise levels of two low-sensitive allpass filter structures, namely wave digital circulator filters (WDCF) and lossless digital integrator filters (LDIF), are compared. Allpass filters are of interest for design of lowpass and bandpass lattice filters. The results show, primarily, that second-order LDIFs have lower total quantization noise gains than corresponding WCDFs for any pol...
متن کاملA General Family of Multivariable Digital Lattice Filters
Absfruct-Lattice structures are developed for the realization of M -input p-output discrete-time all-pass transfer matrices H(z), given in the form of a right matrix-fraction description (MFD): H(r) = N(z) D’ (z). The procedure is based on the generation of a sequence of all pass matrices of successively decreasing order, by matrix LBR two-pair extraction. Two cases are distinguished: the first...
متن کاملUsing Lattice Boltzmann Method to Investigate the Effects of Porous Media on Heat Transfer from Solid Block inside a Channel
A numerical investigation of forced convection in a channel with hot solid block inside a square porous block mounted on a bottom wall was carried out. The lattice Boltzmann method was applied for numerical simulations. The fluid flow in the porous media was simulated by Brinkman-Forchheimer model. The effects of parameters such as porosity and thermal conductivity ratio over flow pattern and t...
