Bu çalışmada, basit ve yeni bir yaklaşımla süzgecin tüm frekans yanıtı parametrelerini kontrol ederek yüksek performanslı bir sonlu dürtü yanıtlı (Finite Impulse Response - FIR) süzgeç tasarım yöntemi geliştirilmiştir. Bu amaçla, geçirme ve durdurma bandı dalgalanmaları, durdurma bandı zayıflaması, geçiş bandı genişliği ve doğrusal faz yanıtı parametrelerinin tamamı göz önünde bulundurularak ve sonsuz dürtü yanıtlı (Infinite Impulse Response - IIR) süzgecin daha iyi frekans yanıtına sahip olma avantajları da kullanılarak IIR süzgeç temelli optimal FIR süzgeç tasarlanmıştır. Butterworth ve Chebyshev süzgeçlerin parametreleri, Yapay Arı Kolonisi (Artificial Bee Colony - ABC) ve Parçacık Sürü Optimizasyonu (Particle Swarm Optimization - PSO) algoritmaları ve çeşitli uzaklık ölçütleri kullanılarak yeni uygunluk fonksiyonlarıyla optimize edilmiştir. Süzgeçlenen işaretler görsel olarak incelendiğinde, önerilen algoritma ile süzgeçlenen işaretin faz gecikmesinin geleneksel süzgeçlere göre daha az olduğu görülmüştür. Ayrıca, tasarlanan süzgecin performansı, dört farklı frekans içeren sinüzoidal bir işareti alt bantlarına ayrıştırmak için test edilmiştir. Sayısal sonuçlara göre, önerilen yaklaşımla tasarlanan süzgeç, işareti diğer yaygın olarak kullanılan geleneksel süzgeçlere göre daha hassas bir şekilde ayrıştırmıştır.

The HLS of digital filters is a complex optimization task in electronic design automation that increases the level of abstraction for designing and scheming digital circuits. The complexity of this issue attracting the interest of the researcher and solution of this issue is a big challenge for the researcher. The scientists are trying to present the various most powerful methods for this issue, but keep in mind these methods could be trapped in the complex space of this problem due to own weaknesses. Due to shortcomings of these methods, we are trying to design a new framework with the mixture of the phases of the powerful approaches for high level synthesis of digital filters in this work. This modification has been done by merging the chimp optimizer with sine cosine functions. The sine cosine phases helped in enhancing the exploitation phase of the chimp optimizer and also ignored the local optima in the search area during the searching of new shortest paths. The algorithms have been applied on 23-standard test suites and 14-digital filters for verifying the performance of the algorithms. Experimental results of single and multi-objective functions have been compared in terms of best score, best maxima, average, standard deviation, execution time, occupied area and speed respectively. Furthermore, by analyzing the effectiveness of the proposed algorithm with the recent algorithms for the HLS digital filters design, this can be concluded that the proposed method dominates the other two methods in HLS digital filters design. Another prominent feature of the proposed system in addition to the stated enhancement, is its rapid runtime, lowest delay, occupied area and lowest power in achieving an appropriate response. This could greatly reduce the cost of systems with broad dimensions while increasing the design speed.

“…However, this filter design has the disadvantage of requiring complicated and enormous computation processing for adjusting the ripples of the bands and the width of the transition-band. In contrast to previous studies [18], [25], Frequency Response Masking (FRM)based filters outperform other designed filters in terms of the transition bandwidth and maximum passband ripple for a given order of filter within an acceptable limit [17], [19], [28]. Recently, Roy and Chandra reported enhanced FRM method using an interpolated band-pass filter, resulting in novel FRM-based filters with more excellent frequency characteristics [28].…”

“…The basic idea for the design of MAXFLAT FIR filters is to use a mathematically proved closed-form solution which satisfies MAXFLAT constraints at the ends of the frequency band and is mapped to the transfer function for the computation of coefficients of filters [6]- [13]. However, classical design involves approximation of the desired frequency response by some suitable closed-form polynomial [14]- [18] because such a closed-form solution mainly focuses on the flatness of the filter but not on the exact frequency response [11]- [13]. Several methods and implementation tricks have been proposed for the design of MAXFLAT FIR half-band filters [15], [16], [19], [20].…”

“…This method allows closed-form parameters for simple and direct computation, but there occur non-negligible amplitude distortions in the stopband and passband. San-José-Revuelta et al have reported an intelligence metaheuristic-based iterative method using multi-fitness function combined with a weighted error function [18]. However, this filter design has the disadvantage of requiring complicated and enormous computation processing for adjusting the ripples of the bands and the width of the transition-band.…”

Design of FIR Half-Band Filter With Controllable Transition-Band Steepness

et al. 2021

Maximally flat (MAXFLAT) half-band filters usually have wider transition-band than other filters although the frequency response is maximally flat (i.e., no ripples) in the passband and stopband. This is due to fact that the maximum possible number of zeros at z = ±1 is imposed in half-band close form solution, which leaves no degree of freedom, and thus no independent parameters for direct control of the frequency response. This paper describes a novel method for the design of FIR half-band filters with an explicit control of the transition bandwidth. The proposed method is based on a generalized Lagrange halfband polynomial (g-LHBP) with coefficients parameterizing a 0-th coefficient h 0 and allows the frequency response of this filter type to be controllable by adjusting h 0 . Then, h 0 is modeled as a steepness parameter of the transition-band and this is accomplished through theoretically analyzing a polynomial recurrence relation of the g-LHBP. This method also provides explicit formulas for direct computation of design parameters related to choosing a desired filter characteristic (by a reasonable trade-off between the transition-band sharpness and passband & stopband flatness). The examples are shown to provide a complete and accurate solution for the design of such filters with relatively sharper transition-band steepness than other existing half-band filters.
