High Order Transformations for Flexible IIR Filter Design
نویسندگان
چکیده
Extensions of popular transformations for IIR filters are given which employ high order mapping filters. Easy control of prototype transfer function features in multiband renditions is demonstrated. A wider interpretation of transformation is also suggested which permits “less-than-N-band replication” (at a cost in dimensionality , phase fidelity and attention to stability enforcement) that is believed to be of considerable benefit in practical design situations.

Design of Optimal Digital IIR Filters using the Genetic Algorithm
This paper presents an evolutionary design of digital IIR filters using the genetic algorithm (GA) with modified genetic operators and real-valued encoding. Conventional digital IIR filter design methods involve algebraic transformations of the transfer function of an analog low-pass filter (LPF) that satisfies prescribed filter specifications. Other types of frequency-selective digital filters...
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 کاملLow latency IIR digital filter design by using metaheuristic optimization algorithms
Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...
متن کاملCustom Designed High-Order Frequency Transformations for IIR Filters - Circuits and Systems, 1995., Proceedings., Proceedings of the 38th Midwest Symposium on
This paper addresses high-order frequency transformation and extends standard Constantinides, Mullisfiranchitti transformations and the exact N-point approach we have previously reported. Using specially designed M* order allpass filters, mapping of N features of the prototype filter can be carried out independently (where N<M). The mapping filter is designed taking special care to ensure that ...
متن کاملDirect Design of Parallel second-order filters for Instrument Body Modeling
This paper 1 presents a direct design technique for parallel second-order sections based on a perceptually motivated logarithmic scale, with application to instrument body modeling. Traditional FIR and IIR design techniques work on a linear frequency scale, which is usually not optimal for audio applications. Warped filters and Kautz filters are good candidates for perceptually motivated filter...
