Suppressing of Power Line Artifact From Electroencephalogram Measurements Using Sparsity in Frequency Domain
Electroencephalogram (EEG) plays an important role in brain disease diagnosis and research of brain-computer interface (BCI).However, the measurements of EEG are often exposed to strong interference of power line artifact (PLA).Digital notch filters (DNFs) can be applied to remove the PLA effectively, but it also results in severe signal distortion
