چکیده
embedded orthogonal transition matrix to the a-ertended upper Hessenberg form, and (iii) factorization of this new form into Givens (planar) rotations. Appropriately interconnecting the rotors leads to the pipelined orthogonal filter structure. As a consequence of our approach, for the SISO case, an essentially orthogonal structure is obtained for the inverse filter; only one of the Givens rotors gets replaced by a hyperbolic rotor. 2-1

Design of IIR Digital Filter using Modified Chaotic Orthogonal Imperialist Competitive Algorithm (RESEARCH NOTE)
There are two types of digital filters including Infinite Impulse Response (IIR) and Finite Impulse Response (FIR). IIR filters attract more attention as they can decrease the filter order significantly compared to FIR filters. Owing to multi-modal error surface, simple powerful optimization techniques should be utilized in designing IIR digital filters to avoid local minimum. Imperialist compe...

متن کاملDesign of Equiripple FIR Filters Using a Feedback Neural Network - Circuits and Systems II: Analog and Digital Signal Processing, IEEE Transactions on
The weighted least squares design of FIR filters is implemented in terms of a feedback neural network. The proposed neural network is shown to converge to the global minimum in each iteration for the current weighting function, and as the weighting function is adjusted from iteration to iteration, an equiripple design is achieved. The approach is applicable to FIR filters with piecewise-constan...
متن کاملMinimization of L2-sensitivity for state-space digital filters subject to L2-dynamic-range scaling constraints
The problem of minimizing an L2-sensitivity measure subject to L2norm dynamic-range scaling constraints for state-space digital filters is formulated. It is shown that the problem can be converted into an unconstrained optimization problem by using linear-algebraic techniques. Next, the unconstrained optimization problem is solved by applying an efficient quasi-Newton algorithm with closed-form...
