Question

When does a signal say to be bounded?

(a) When it is stable

(b) When it gives slow responses

(c) Magnitude does not grow without bound

(d) When it has small inputs

This question was addressed to me in final exam.

This interesting question is from BIBO Stability & Systems in the Time Domain in division Signals and Systems Basics of Signals and Systems

Answer 1

The correct option is (c) Magnitude does not grow without bound

Easiest explanation: A signal x(t) is said to be bounded if its magnitude does not grow without bound.

i.e |x(t)|≤Bx<∞.
