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:
“What a phenomenon it has been—science fiction, space fiction—exploding out of nowhere, unexpectedly of course, as always happens when the human mind is being forced to expand; this time starwards, galaxy-wise, and who knows where next.”
—Doris Lessing (b. 1919)
