1)
Identify the methods implemented for denoising or removing artifacts from a raw EEG signals:
Independent component Analysis(ICA)
Principal Component Analysis(PCA)
Wavelet Transform(WT)
All the above
2)
Ocular artifacts, Muscle artifacts, Cardiac artifacts are:
Extrinsic artifacts
Intrinsic artifacts
Experimental artifacts
Environmental artifacts
3)
Artifacts are unwanted signals which are mainly originated from:
Environment noise
Experimental error
Physiological artifacts
All the above
4)
The filtering methods employed for the cancellation of various noises from a EEG signals
Adaptive ï¬Âltering
Wiener ï¬Âltering
Welch Method
Both A and B
5)
Band pass filtering used to remove electromyogram (EMG) contamination:
30-40 Hz Band pass Filtering
60 Hz Band pass Filtering
1-20 Hz Band pass Filtering
70-100 Hz Band pass Filtering
