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