Multiple choice

The time required for a pulse to decrease from 90 to 10 percent of its maximum value is called

  1. rise time

  2. decay time

  3. binary level transition period

  4. propagation delay

B Correct answer
Explanation

Decay time specifically measures how long a pulse takes to fall from 90% to 10% of its maximum value. Rise time would measure the opposite (10% to 90%), while propagation delay is the time for a signal to travel through a circuit.
