A few words on the second edition. By a nice coincidence, Springer's proposal to revise the
book came when I was giving a serious thought to the idea. Ten years have passed and my …

The many advancements in the area of numerical optimization in conjunction with the ever-
increasing power of computers have made optimization-based filter design an increasingly …

This paper presents a method for the frequency domain design of infinite impulse response
(IIR) digital filters. The proposed method designs filters approximating prescribed magnitude …

Vector fitting (VF) is a popular iterative rational approximation technique for sampled data in
the frequency domain. VF is nowadays widely investigated and used in the Power Systems …

This paper presents a two-stage approach for designing an infinite impulse response (IIR)
notch filter. First, the numerator of the transfer function of the IIR notch filter is obtained by …

In this paper, the design problems and applications of the fractional Hilbert transformer
(FHT) are investigated. First, the conventional Hilbert transformer is generalized to FHT. Its …

In this paper, minimax design of infinite-impulse-response (IIR) filters with prescribed
stability margin is formulated as a conic quadratic programming (CQP) problem. CQP is …

In this paper, a weighted least-squares method is presented to design one-dimensional and
two-dimensional variable fractional delay allpass filters. First, each coefficient of the variable …

A novel approach to designing approximately linear phase infinite-impulse-response (IIR)
digital filters in the passband region is introduced. The proposed approach yields digital IIR …

In this paper, a novel method for IIR digital filter design using iterative second-order cone
programming (SOCP) is proposed under the minimax criterion. The convex relaxation …
