2.An impulse that, in a neutral circuit, causes the loop to open or causes absence of signal. In a polar circuit it causes the loop current to flow in a direction opposite to that for a mark impulse. A spaceimpulse is equivalent to abinary zero.
4.In a period of over 1,000 years, every new arrival set to carve out a cave in an open space on the cliff on a sudden impulse. No one has ever made any demonstration and calculation based on structural mechanics.
