In order to analyze our data as accurately as possible, it is important that we filter out the extreme high and low frequency waves in our data, as these recordings are most likely due to the environment and other artifacts. Typically, frequencies less than 0.01 Hz - 0.1 Hz and greater than 40 Hz - 50 Hz are filtered out. BESA automatically turns on low and high cutoff filters that can be edited if desired. Keep in mind that filters distort data, and filtering too much can alter waveforms and wave amplitudes significantly.
