I Think this signal if for display hour of the Mistral-Nework (Network of buses for the town). There are four main ways to deal with artifacts depending on the data analysis: The first approach is to select and reject EEG epochs with artifacts. It might seem impossible to you that all custom-written essays, research papers, speeches, book reviews, and other custom task completed by our writers are both of high quality and cheap. (it might be a satellite but that is what I think). the , . 2010). As noise is usually uncorrelated and independent from EEG sources, we can observe that some components include the artifact information. ", Found this extremely odd, almost constant signal in the.
