Preshoot, Overshoot, Ringing

Preshoot and overshoot are peak distortions preceding/following an edge. Ringing is the positive-peak and negative-peak distortion, excluding overshoot, on pulse top or base. For example, a combined preshoot, overshoot, and ringing specification of 5% implies:

Overshoot/undershoot < 5%

Largest pulse-top oscillation <+ 5%, of pulse amplitude.

Overshoot
e.g. 5%			Ringing (POSITIVE)
			e.g. +3%
100%
Amplitude
			Ringing (NEGATIVE)
			e.g. 2%
0% Amplitude			e.g. 2%
			Preshoot


			e.g. 2%

Settling Time

Time taken for pulse levels to settle within level specifications, measured from 90% point on leading edge.
