Processing raw EEG signals in MATLAB requires loading them into the program first. To achieve this, we need to utilize MATLAB's file input functionality, which enables reading data files from the computer's hard drive and loading them into the MATLAB workspace. Key functions like load, readtable, or fscanf can be employed depending on the file format (e.g., .mat, .txt, .edf). For instance, binary EEG files may require specifying data precision and dimensions during import. Once the raw EEG signals are successfully loaded into MATLAB, we can proceed with signal processing and analysis tasks such as noise removal, filtering, time-domain analysis, and frequency-domain analysis. Common implementations include using built-in functions like filter for bandpass filtering or custom algorithms for artifact removal, followed by spectral analysis with fft for frequency-domain insights.
