wander vi. 1.(无目的地)漫步;漫游;徘徊,彷徨;流浪,漂移。 2.迷路;走岔,离开。 3.(河)曲曲折折地流;(山脉)蜿蜒错列。 4.(思想等)离开正道;错乱;离题乱说。 5.【医学】游走。 wander from the subject (谈话)离开本题。 His mind is wandering .他心不在焉。 His wits are wandering. 他有点疯了。 vt. 〔诗〕漫游。 wander about 徘徊,彷徨,流浪。 n. 徘徊,彷徨,流浪。 n. -er 1.漫游者,流浪汉。 2.彷徨者;迷路的动物。
However , this induces baseline wander 然而,这又会发生基线偏移。
We propose to mitigate baseline wander either by using a line code or by using active baseline restoration 我们使用线性编码或者使用在接收器上活性基线恢复来去除基线偏移。
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 论文的主要研究工作:一、研究了原始心电信号的滤波方法,提出了滤除各种干扰的数字滤波器的设计方法,包括50hz及其谐波、肌电干扰和基线漂移等。
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 在对大量文献进行比较、研究的基础上,针对不同的临床应用目的,提出了各种滤波器的选用准则:在心律失常分析中选用整系数低通数字滤波器对原始心电信号进行滤波;在对心率变异信号进行分析时需先用低通滤波器滤波然后再采用全通减低通方法设计的高通滤波器或者一次性滤波器进行滤波。
