False detection margin, or Min, is the margin between the detection threshold and the highest noise level (see Equation 2 and Equation 3 andFigure 8 ).

This parameter is of particular interest, because it expresses how much margin exists to protect against a false touch detection. For example, if Th = 1% and N = 0.5%, then the false detection margin is a 0.5% change. Because the margin is 50% of the threshold, that implies that the noise level would have to double for a false touch detection to occur.
