In signal processing, the half time is the time it takes for the amplitude of a pulse to drop from 100% to 50% of its peak value.
Famous quotes containing the word time:
“When you get out on one of those lakes in a canoe like this, you do not forget that you are completely at the mercy of the wind, and a fickle power it is. The playful waves may at any time become too rude for you in their sport, and play right over you.”
—Henry David Thoreau (1817–1862)
