            Abstract : 
The notch selectivity of a notch filter is defined as the halfpower selectivity of a feedback amplifier with an open-loop gain of 40dB and the notch filter in its feedback circuit. Parameters of the exponential, the trigonometric, and the hyperbolic RC lines for different selectivities are given.
