Incorporating Directionality in Transversal-Resonator-Based Bandpass Filters With Tunable Transfer Function Characteristics

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2023
This paper introduces a detailed methodology for the realization of multi-functional transversal resonator-based non-reciprocal bandpass filters (NR-BPFs) that combine the functionality of a single-/multi-band BPF and an RF isolator.

3-D models and structural analysis of rock avalanches: the study of the deformation process to better understand the propagation mechanism [PDF]

Earth Surface Dynamics, 2016
Rock avalanches are extremely destructive and uncontrollable events that involve a great volume of material (> 106 m3) and several complex processes, and they are difficult to witness. For this reason the study of these phenomena using analog modeling

An Electrically Programmable Split-Electrode Charge-Coupled Transversal Filter (EPSEF) [PDF]

, 1979
A CCD split-electrode transversal filter (EPSEF) with analog controlled tap weights is described. The programmable tap weighting utilizes a novel analog multiplier for sampled data, based on charge profiling underneath a resistive gate structure.

Programmable transversal filter

Electronics Letters, 1981
A programmable transversal filter is presented, based on the combination of a dynamic amplifier and a bucket-brigade-device analogue delay line. Experimental results are presented, indicating the suitability for a complete monolithic filter realisation.

Cascade Structure for Finite Impulse Response Filters and Linear Prediction

Ingenius: Revista de Ciencia y Tecnología, 2012
This paper presents a complete analysis of the cascade structure for adaptive transversal filters based on adaptive algorithms. The standard structure of the cascade transversal FIR filter is obtained by replacing the whole structure by small ones with ...

Nonlinear Performance on Acoustic Transversal Filters

2020 IEEE International Ultrasonics Symposium (IUS), 2020
The recently proposed transversal topology for creating acoustic filters allows to achieve arbitrary filter responses, in terms of position of transmission zeros and bandwidth, among others. This new topology might indeed help to give response to the demanding filter specification of the recent and future wireless communication systems, some not yet ...

Low-complexity RLS algorithms using dichotomous coordinate descent iterations [PDF]

, 2008
In this paper, we derive low-complexity recursive least squares (RLS) adaptive filtering algorithms. We express the RLS problem in terms of auxiliary normal equations with respect to increments of the filter weights and apply this approach to the ...
