baseline wander 中文意思是什麼
baseline wander
解釋
基線跳動,基線漂移-
After compared lots of literatures and methods, we offer the norm for selecting different filters. that is to say, in arrhythmia analysis, the integer coefficient lowpass filter is adopted, while in heart rate variability analysis, the high pass filter designed by all - pass minus low - pass filter or filter which can remove both baseline wander and 50hz power - line frequency at one time is used
在對大量文獻進行比較、研究的基礎上，針對不同的臨床應用目的，提出了各種濾波器的選用準則：在心律失常分析中選用整系數低通數字濾波器對原始心電信號進行濾波；在對心率變異信號進行分析時需先用低通濾波器濾波然後再採用全通減低通方法設計的高通濾波器或者一次性濾波器進行濾波。 -
We propose to mitigate baseline wander either by using a line code or by using active baseline restoration
我們使用線性編碼或者使用在接收器上活性基線恢復來去除基線偏移。 -
However, this induces baseline wander
然而，這又會發生基線偏移。 -
The main works in this paper are as follows : first ， the preprocessing of ecg signal - filtering is carried on. the interference includes 50hz and its higher harmonics, muscle artifact and baseline wander and so on
論文的主要研究工作：一、研究了原始心電信號的濾波方法，提出了濾除各種干擾的數字濾波器的設計方法，包括50hz及其諧波、肌電干擾和基線漂移等。
