Ah.vtrud-This paper presents realisation techniques for IIR digital filters based on the primitive operatur graph synthesis methud. The appruach exploits the redundancy present in the filter multiplier structure when the cuefficients are invariant allowing partial result reuse thruughuut the filter structure. Results are presented fur a range of elliptic filters with varying wordlength and order, realised using direct form, parallel and cascade structures. These show significant savings when compared with the equivalent canonical signed digit multiplier coding scheme.

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...

Comparison of Different Techniques to Design an Efficient FIR Digital Filter

Digital filters are commonly used as an essential element of everyday electronics such as radios, cell phones, and stereo receivers. Digital filters may be more expensive than an equivalent analog filter due to their increased complexity, but they may lead to many designs which are impractical or impossible as analog filters. Basically there are two types of digital filters, which are FIR (Fini...

Low 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...

Magnitude Approximation of IIR Digital Filter using Greedy Search Method

The paper presents a greedy search method based on binary successive approximation-evolutionary search (BSA-ES) strategy to design stable infinite impulse response (IIR) digital filter using L1 optimality criterion. The stability constraints are well taken care of during the design procedure. The filter designed based on L1-approximation error possesses flat pass-bands and stop-bands to that of...

and key words In this paper, we consider the array processors implementation of the infinite impulse response (11R)1-D and 2-D digital filters that require recursive computations . We use the state space representation to obtain, in a straight forward manner, efficient implementation via dynamically switchable systolic arrays (cylindrical type) of 1 -D direct realisation .
