WebThe EEG signal, a recording of the brain activity using multiple electrodes placed on the scalp, can be hardly contaminated by a lot of noises called artifacts. The artifacts are generated by the action of the skeletal muscles such as: eye movements, jaw clenching, etc. Indeed, the signals recorded are mixture of phenomenon from multiple generators. …
In signal processing, a filter is a device or process that removes some unwanted components or features from a signal. Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal. Most often, this means removing some frequencies or … See more Linear continuous-time circuit is perhaps the most common meaning for filter in the signal processing world, and simply "filter" is often taken to be synonymous.
