A new method is proposed for designing IIR digital allpass filters with an equiripple phase
response that can be proven to be optimal in the Chebyshev sense. The proposed …

Analysis, design, and realization of digital filters have experienced major developments
since the 1970s, and have now become an integral part of the theory and practice in the field …

This brief proposes a new method for designing digital all-pass filters with a minimax design
criterion using second-order cone programming (SOCP). Unlike other all-pass filter design …

In recent years, genetic algorithms (GAs) began to be used in many disciplines such as
pattern recognition, robotics, biology, and medicine to name just a few. GAs are based on …

This paper considers the minimax design of digital all-pass filters via the FIR and IIR
approximations. For the FIR digital all-pass filter design, the problem is appropriately …

The multiobjective design of digital filters using spiral optimization technique is considered
in this paper. This new optimization tool is a metaheuristic technique inspired by the …

The design of two-channel linear-phase quadrature mirror filter (QMF) banks constructed by
real infinite impulse response (IIR) digital all-pass filters is considered. The design problem …

This paper presents a new direct design of infinite-impulse response (IIR) filters with a flat
magnitude response in both passband and stopband (Butterworth filters). The design …

This paper presents a multiple exchange algorithm for designing linear phase equiripple FIR
notch filters. The algorithm is first discussed for designing a single notch filter. Compared …

The two-channel QMF filter bank based on allpass sections is one of the best known circuits
for building up a multi-channel filter bank for signal compression. An analysis–synthesis …
