Stability of Linear Predictive Structures using IIR Filters
نویسنده
چکیده
Considered are general, pure linear prediction schemes, where the prediction of the current sample is based on IIR-filtered past samples. Properties of these schemes are discussed, in particular, the whitening property, the realisation of the synthesis filter and its stability. The realisation problem as occurring in warped linear prediction is solved. Furthermore, it is proved that, at least for a specific class of systems, data input windowing for the calculation of the optimal prediction coefficients guarantees the stability of the synthesis filters. Keywords—LPC, IIR-filters, stability.

متن کاملAdaptive Line Enhancement Using a Parallel IIR Filter with A Step-By-step Algorithm
A step-by-step algorithm for enhancement of periodic signals that are highly corrupted by additive uncorrelated white gausian noise is proposed. In each adaptation step a new parallel second-order section is added to the previous filters. Every section has only one adjustable parameter, i.e., the center frequency of the self-tuning filter. The bandwidth and the convergence factor of each secti...
متن کاملDesign 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 کاملA Procedure for Quasi-Equiripple Linear-Phase IIR Filters Design
The linear-phase IIR filters are described in many cases, mainly due to distortion-free transmission of signals. One of the major problems of IIR filter design is stability, which can be obtained with suitable value of group delay τ . This paper concerns calculation of filter order N and group delay τ in case of quasi-equiripple design of IIR filters. We propose a novel procedure for determinin...
