Filter: Alter Notch filter formula to remove /0 and allow perfect notch.
...
This formulation of the notch equations lets the user specify the depth of the Notch. The presence of a diveide by A prevents the gain going to zero and therefore achieving a perfect notch. It also provides the risk that a user may attempt to do this and cause a divide by zero error. This change adds the ability to achive a perfect notch and removes the possibility of a divide by zero.
