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