A short pulse is created by reducing ringing. Which option best describes this statement?

• A. Both
• B. True
• C. False
• D. Not related

Answer: (B)

The idea being tested is how damping and ringing affect pulse width. Ringing refers to lingering oscillations after a fast transition. Those oscillations extend the waveform in time, making the pulse last longer. By reducing ringing — i.e., increasing damping so the oscillations decay quickly — the waveform settles sooner and the effective duration of the pulse becomes shorter. That’s why a short pulse is created when ringing is reduced. In practice, damping or proper termination shortens the tail of the pulse, though excessive damping can reduce amplitude or slightly distort shape. So the statement is true.
