VVC In-Loop Filters [PDF]

open access: yesIEEE Transactions on Circuits and Systems for Video Technology, 2021
This paper presents an overview of the technologies for in-loop processing and filtering in the Versatile Video Coding (VVC) standard. These processes comprise luma mapping with chroma scaling, deblocking filter, sample adaptive offset, adaptive loop filter and cross-component adaptive loop filter.

Memristor-Based Loop Filter Design for Phase Locked Loop [PDF]

open access: yesJournal of Low Power Electronics and Applications, 2019
The main challenge in designing a loop filter for a phase locked loop (PLL) is the physical dimensions of the passive elements used in the circuit that occupy large silicon area.

Passive Loop Filter Assistance for CTSDMs [PDF]

open access: yesIEEE Transactions on Circuits and Systems II: Express Briefs, 2017
This brief presents a power reduction technique for continuous time sigma–delta modulators (CTSDMs). The approach consists of two elements. First, a passive low-pass filter is added in front of the modulator’s loop filter to reduce the high frequency components in the loop.

Loop modeling: Sampling, filtering, and scoring [PDF]

open access: yesProteins: Structure, Function, and Bioinformatics, 2008
AbstractWe describe a fast and accurate protocol, LoopBuilder, for the prediction of loop conformations in proteins. The procedure includes extensive sampling of backbone conformations, side chain addition, the use of a statistical potential to select a subset of these conformations, and, finally, an energy minimization and ranking with an all‐atom ...

Analysis of a multi-wavelength time-resolved observation of a coronal loop [PDF]

open access: yes, 2005
Several items on the diagnostics and interpretation of coronal loop observations are under debate. In this work, we analyze a well-defined loop system detected in a time-resolved observation in several spectral bands.

Application and Optimization of Kalman Filter for Baseband Signal Processing of GPS Receivers

open access: yesMATEC Web of Conferences, 2016
High sensitivity tracking in GPS receiver is required in many weak signal circumstances. The key of improving sensitivity is the optimization of the loop filter in tracking.

Design of Compact Multiband Microstrip BPF Based on Fractal Open-Ring Configuration [PDF]

open access: yesEngineering and Technology Journal, 2018
Multiband bandpass filters (BPFs) are one of the core elements in the multi-services wireless communication systems. For this purpose, this paper presents a design of a compact multiband microstrip BPF design based on fractal open loop configuration. The

All-Digital Timing Recovery for Free Space Optical Communication Signals With a Large Dynamic Range and Low OSNR

open access: yesIEEE Photonics Journal, 2019
The free space optical communication (FSOC) signals often exhibit a much larger dynamic range and much lower OSNR than optical fiber communication signals, due to the large-scale relative motion of the terminals, change of atmospheric channel conditions ...

A 5-MHz 11-bit delay-based self-oscillating ΣΔ modulator in 0.025 mm2 [PDF]

open access: yes, 2010
In this paper a self-oscillating Sigma Delta modulator is presented. By introducing this self-oscillation in the system, the loop filter operates at a speed significantly lower than dictated by the clock frequency.

Multi loop snare technique for difficult inferior vena cava filter retrievals

open access: yesCVIR Endovascular, 2018
Introduction Use of optional vena cava filters has steadily increased. In the majority of cases removal is successful using standard techniques. In cases of tilting and migration of the filter however, more advanced techniques are necessary.
