1. An alpha-wave amplitude slicer comprises:

  • a window slicer that receives an alpha wave as an input, outputs a first high pulse when the alpha wave exceeds a high threshold slice level and a window pulse when the alpha wave enters an intermediate region between the high and a low threshold slice level, the alpha wave remains below the high threshold slice level and the alpha wave falls below the low threshold slice level at a trailing edge; and

    an RS flip-flop connected to the window slicer that outputs a high-alpha phase mark based on the first high pulse and a low-alpha phase mark based on the window pulse and neglects any second high pulse output between the generation of the above first high pulse and that of the next window pulse.
