TL;DR: In this paper, a simple procedure, applicable to any high order transfer function (n≥3), is described, which generates a family of transfer functions possessing identical phase/frequency responses but distinct gain/frequency response.
Abstract: A simple procedure, applicable to any high order transfer function (n≥3), is described, which generates a family of transfer functions possessing identical phase/frequency responses but distinct gain/frequency responses. By application to a 10th-order all-pole Bessel function, it is shown that selected members of this particular family have significantly wider gain-bandwidths and correspondingly improved time domain behaviour.

TL;DR: This technique in comparison with the conventional Sinc filter used for wideband signals does not need to a large number of changing terms for the filter and also speeds up the convergence.
Abstract: An adaptive algorithm for estimating the delay between two noisy wideband signals is presented. The method is based on the explicit time delay estimation and breaks the fractional delay filter into two parts, one as the pre-filter and the other as the fractional part. The adaptation changes the second filter. A bias free estimate of the delay is produce, which is showed to be convergent in both mean and variance. This technique in comparison with the conventional Sinc filter used for wideband signals does not need to a large number of changing terms for the filter and also speeds up the convergence.

TL;DR: In this paper, a memristor based active low pass Bessel filter was presented, where resistor elements were replaced by memristors and the circuit was analyzed by on frequency response.
Abstract: Bessel filter is a type of linear form filter, which is widely used for applications where constant group delay response is required. Such implementation allows to avoid linear distortion. It is believed that recent realization of memristor element can significantly affect filter's performance by being able to adjust filter gain and cut-off frequency. Therefore, this paper presents a memristor based active low pass Bessel filter, where resistor elements were replaced by memristors. The circuit is analysed by on frequency response. Memristor resistances are to be adjusted by means of tuning circuits. Overall, memristive circuit resulted in slight deviation from the original circuit with the same power consumption and verified adjustability of several filter characteristics.

Abstract: In this paper, the fractional Bessel wavelet transform is introduced by exploiting the theory of the fractional Hankel transform and the boundedness of the fractional Bessel wavelet transform obtained. Time invariant linear filter associated with the fractional Hankel transform is investigated and its various properties are obtained. In the present paper, authors also expressed time-invariant linear filters in the form of the fractional Bessel wavelet transform and applications of the aforesaid filters in the integral equation are given.

TL;DR: In this paper, a 2D method for Bessel Gaussian beam azimuthal and radial decomposition using digital holograms is proposed, and the reconstruction of the amplitude, phase and index of the field with high degree of accuracy.
Abstract: We propose a 2-dimensional method for Bessel Gaussian beam azimuthal and radial decomposition using digital holograms. We illustrate the reconstruction of a Bessel Gaussian beam after encountering an obstruction. From the measured decomposition we show the reconstruction of the amplitude, phase and azimuthal index of the field with high degree of accuracy.
