Description: REMOVAL OF NOISE FROM ECG (ELECTROCARDIOGRAPHY) BY USING MATLAB.
EEG (Electroencephalograph) recording from the scalp has biological artifacts and external artifacts. Biological artifacts, which are generated, can be EMG (Electromyography) signal, EOG (Electrooculograph) signal or ECG (Electrocardiograph) signal. These artifacts appear as noise in the recorded EEG signal individually or in a combined manner. Usually physicians are misled by these noisy signals and the EEG analysis can go wrong. This paper presents noise cancellation i.e. removal of noise signal which can be either EMG, ECG or a combination of these two artifacts from the corrupted EEG signal and also signal enhancement both using recurrent learning technique. For this purpose, we have implemented the RTRL (Real Time Recurrent Learning) algorithm,

Description: In numerous application areas, including biomedical engineering, radar, sonar and digital communi-
cations, the goal is to extract a useful signal corrupted by interferences and noises. Noise/interference
removal is facilitated when multiple sensors on di erent locations record the biomedical phe-
nomenon simultaneously.
For instance in recordings taken from the mother s skin during pregnancy, the electrical activity
from the fetal heartbeat can be masked by the stronger maternal cardiac activity. In electrocar-
diogram (ECG) recordings from atrial brillation su erers, the electrical activity from the atria
appears mixed with that from the ventricles. In electroencephalogram (EEG) recordings from
epileptic patients, epileptic discharges and the brain s background activity contribute simultane-
ously to the signals measured by scalp electrodes, and can be further corrupted by artifacts such
as eye blinks or body movements. Platform: |

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: |
