When does a signal say to be bounded?

A)

When it is stable

B)

When it has small inputs

C)

Magnitude does not grow without bound

D)

When it gives slow responses

Correct Answer : Option (C) : Magnitude does not grow without bound

Explanation : A signal x(t) is said to be bounded if its magnitude does not grow without bound.
i.e |x(t)|≤Bx<∞.
