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:
“If youth is the period of hero-worship, so also is it true that hero-worship, more than anything else, perhaps, gives one the sense of youth. To admire, to expand one’s self, to forget the rut, to have a sense of newness and life and hope, is to feel young at any time of life.”
—Charles Horton Cooley (1864–1929)
