I suggest that you

  1. change the corner frequency to 10 Hz as I suggested last week. This filter, as it is, is going to give you trouble.
  2. Put in a sine wave at 3.4283 Hz with an amplitude of 1, rather than white noise. In this way, its not necessary to do any subtraction. Just make PSD of the output of each filter.
  3. Be careful about window length and window function. If you don't do this carefully, your PSD will be polluted by window bleeding.
