Description: 在心电信号的采集过程中，会引入各种干扰噪声，如基线漂移。为了得到不失真的心电信号，在诊断分析前要对信号进行预处理---数字滤波。
FIR滤波器容易实现线性相位。对于相位要求严格的场合，要求用FIR滤波器实现滤波，实验要求用用FIR高通滤波器法去除其中基线漂移。
-ECG acquisition process, will introduce all kinds of interference noise, such as baseline drift. In order to get undistorted ECG in the diagnosis of pre-process the signal before--- digital filter. Linear phase FIR filter is easy to implement. For the phase-critical occasions, asked to use FIR Filter filter, test requirements with a high-pass filter with the FIR in which baseline drift removal.

Description: Abstract— with the latest advancements in electronics,
several techniques are used for removal of unwanted entities
from signals especially that are implied in the most
sophisticated applications. The removal of power line
interference from most sensitive medical monitoring
equipments can also be removed by implementing various
useful techniques. The power line interference (50/60 Hz) is
the main source of noise in most of bio-electric signals. The
report presents the removal of power line interference,
baseline wandering and additive white Gaussian noise
(AWGN) from ECG signal using the different types of
filtering technique. The project is based on digital signal
processing (DSP) techniques with MATLAB package, the
IIR Notch filter can be used for removal of power line
interference, Median can be used for Baseline wandering
noise and Discrete Wavelet Transform can be used for
removal of AWGN. Platform: |
