WebTo eliminate this shift introduced by the filter, we apply the same filter twice to the data. First, we apply the FIR filter to the original input signal, just as we did to create the lowpass filtered EEG. This filtering operation introduces a shift (of size n/2 indices, or 0.05 s for our data) in the resulting EEG (e.g., see above).
