OPTIMAL HANKEL−NORM APPROXIMATION OF IIR BY FIR SYSTEMS (TueAmPO4)
This paper presents a constructive method to (sub)optimal finite impulse response (FIR) approximation of a given infinite impulse response (IIR) model. The method minimizes the Hankel norm of approximation error by using the explicit solution of norm−preserve dilation problem. It has the advantage over the existing methods that it provides an explicitly constructive solution and allows the trad...
متن کاملComputationally efficient weighted least-squares design of FIR filters satisfying prescribed magnitude and phase specifications
An efficient method for the design of FIR filters satisfying prescribed magnitude and phase specifications is described. The method involves formulating an objective function in a quadratic form. The filter coefficients are obtained by solving a system of linear equations which involves either a Toeplitz matrix or a Toeplitz-plus-Hankel matrix. The computational complexity associated with such ...
متن کاملMethod for FIR filters design with compressed cosine using Chebyshev's norm
This paper considers a new method for FIR filters design. The method uses an LN optimality norm. To achieve a better approximating effect, a new modulating function which compresses the oscillations of the cosine is proposed. A parameter sets the gradient of the modulating function, with respect to the oscillations’ compression. The approximating polynomial is carried out using Remez’ exchange ...
متن کاملDesign of Adaptive Filters Using Least Pth Norm Algorithm
Adaptive filters play a vital role in digital signal processing applications. In this paper, a new approach for the design and implementation of adaptive filters say FIR and IIR are analyzed. The filter design is based on least pth norm algorithm and the characteristics of the individual filters are also taken into consideration. Least pth norm algorithm is considered for the design because it ...
متن کاملLow-Order State-Space Models of Head-Related Transfer Function Arrays
Low-order state-space models of collections of head-related transfer functions (HRTFs) are described and found to yield a substantial computational savings relative to conventional filter arrays. Several recent binaural displays model multiple HRTFs simultaneously using an array of independent FIR or IIR filters. As HRTFs are locally redundant it is possible to model collections of HRTFs with a...
