  • Check your group for 12/11 and the assigned parameters of the filters or the different filters.

    1. Search online how the assigned parameter may change the performance of the filter. Please focus on how it would affect the output signal.

The other signals (on the upper graph) were filtered with a 1st-order

    Butterworth HPF with different cut-off frequencies (1 Hz, 20 Hz, 40 Hz, and 80 Hz). The time window

    in this graph was 100 ms in duration. The graph shows the MEP signal 1 ms after TMS trigger. The

    lower graph shows the areas of deviation of the different filtered signals to the unfiltered MEP.
