Figure 10. Digital Filter Response in a typical Intel processor on a 65 nm or 90 nm process. The filter
curves were purposely offset for clarity.
Figure 10 shows the filter in use in a typical system. Note that the two curves have been purposely offset for
clarity. Inserting the filter does not induce an offset as shown.
