Flexible Time-Delay Designs for Harmonic Sequence Filter/Extraction: A Further Generalization of Two-Sample Methods

语言:

中文摘要

时延是导致谐波序列(HS)滤波器/提取器动态响应缓慢的关键因素。本文提出了一种灵活时延设计概念,作为双采样方法(即延迟信号抵消法)的推广,旨在提升HS滤波器/提取器的动态响应速度与鲁棒性。

English Abstract

Time-delay is an inevitable operator causing slow dynamic response of related systems employing harmonic sequence (HS) filters/extractors. This letter presents a new concept of flexible time-delay designs as a further generalization of two-sample methods (i.e., delayed signal cancellation) to improve the dynamic response and robustness of HS filters/extractors. The new concept offers flexible desi...
