pulse
In medicine, the pulse refers to the rhythmic pulsations (expansion and contraction) of an artery in response to the cardiac cycle (heartbeat). The pulse may be felt ( palpated) in any place that allows an artery to be compressed near the surfac ...
to decrease (fall) from a specified value (usually 90% of the peak value exclusive of
overshoot or undershoot) to another specified value (usually 10% of the maximum value exclusive of overshoot or undershoot).
Limits on undershoot and oscillation (also known as
ringing and hunting) are sometimes additionally stated when specifying fall time limits.
