What is the overshoot number?

Finite

Zero

Infinite

More than 10

Correct Answer : Option (A) : Finite

Explanation : The overshoot near discontinuity does not vanish as more and modes are retained. Instead, the overshoot is finite no matter what finite numbers of modes N are retained. Even though the region of overshoot gets progressively smaller as N ↔∞.
