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 کاملRoundoff Noise in FIR Digital Filters and in FFT Calculations
FIR (finite impulse response) digital filters are open loop signal processors. These are numerical filters, and roundoff takes place within these filters when certain numerical operations are performed upon the filter input signals. Roundoff also takes place in IIR (infinite impulse response) digital filters. These are feedback filters, and the effects of quantization in IIR filters are more co...
متن کاملInterpolated Finite Impulse Response (IFIR)
The finite impulse response filters are inherently stable and have linear phase response property. The main drawback of these filters is lies in requirement of higher orders for similar magnitude response compared to Infinite Impulse response filters. Also the amount of computational complexity needed for the implementation of the filter, especially for the filters with narrow transition band i...
متن کاملA Hybrid Infinite/finite Impulse Response (hir) Filter
Filters are used to implement signal transforms, and filter design is a very important part of the signal processing field. There are currently 2 types of filters available: the finite impulse response (FIR) filter, and the infinite impulse response (IIR) filter. While FIR filters have desirable traits such as stability (an absence of poles), IIR filters are able to generate outputs more effici...

This paper discusses a method for designing the Finite Impulse Response (FIR) filters based on polynomial approach.
متن کاملDesign of Low Power and Area Efficient FIR Digital Filter
the impulse response can be either finite or infinite. The methods for designing and implementing these two filter classes differ considerably. Finite impulse response (FIR) filters are digital filters whose response to unit impulse (unit sample function) is finite in duration. This paper presents the design of low power FIR filter and area efficient parallel linear phase FIR digital filter. Lo...
