1·In this paper, a method for ECG baseline drift correction based on smoothing filter is introduced.

介绍了一种基于平滑滤波器的心电基线漂移矫正方法。

2·The system takes ARM as the core and employs signal amplifying, filtering, and anti-baseline drift circuits.

该装置以ARM为核心，包括低功耗的双路心电信号放大、滤波、抗基线漂移电路。

3·Original ECG preprocessing:remove noise such as high-frequency power supply and interference factors such as baseline drift by wavelet function and filter;

原始心电信号的预处理：利用小波降噪函数和滤波器去除电源干扰的高频噪声和基线漂移及抖动等干扰因素；

4·With NIR spectra, the analytical information is contained in small spectral variations and usually dominated by the features such as light scattering, background noise and baseline drift.

近红外光谱不但包含着物质成分信息，而且这些信息完全掩盖在众多复杂背景当中（包括光散射、背景噪声以及背景漂移）。

5·No calibration. No drift. Flat baseline.

无需校准、无漂移、基线平稳。
