The goal of sparse FIR filter design is to minimize the number of nonzero filter coefficients, while keeping its frequency response within specified boundaries. Such a design can be formally expressed via minimization of l0-norm of filter’s impulse

Array pattern with reduced dynamic range ratio (DRR) of excitation coefficients simplifies the design of array's feeding network. However, constraining DRR pushes small coefficients towards higher values, which might not be optimal from the array-pat

Polynomial sharpening is an efficient technique for improving folding band response of cascaded-integrator-comb (CIC) decimation filters. However, the sharpening of folding bands results in a high passband droop, which is intolerable in many applicat

The design of sparse FIR filters leads to combinatorial optimization problems, which can be rarely solved in an acceptable time. Therefore, many approximate methods have been considered. Most of them are focused on the design of linear-phase filters

Hilbert transforms of Gaussian derivatives are related to Dawson's integral. Since this integral cannot be expressed in a closed form, various methods for the approximation of the derivatives have been developed. A closed-form approximation can be ob

Classical imaging system projects the surface of a 3-D object onto a 2-D sensor. The surface occupies only a small part of the observed volume. Therefore, the samples representing the volume form a sparse signal. We exploit this property in reconstru

Folding band sharpening of the cascaded- integrator-comb filter results in a high passband droop. In applications requiring low passband deviation, the droop is reduced by connecting a low-order FIR compensator in cascade with the filter. In this Let

Ultra-wideband (UWB) impulse radio uses very short pulses whose spectra are regularized by Federal Communications Commission (FCC). One technique to obtain these pulses is shaping. The shaping is realized with a bandpass filter called pulse shaper. I

Cascaded-integrator-comb (CIC) decimation filters are the simplest multiplierless filters supporting high sample rate conversion factors. However, the magnitude response of high order CIC filters exhibits a high passband droop. Such a droop can be re

A simple multiplierless decimation filter is cascaded-integrator-comb (CIC) filter. However, the CIC filter offering high folding-band attenuations introduces a high passband droop. The most popular technique for reducing the droop is connecting a lo
