Which of the following is true about the bounded signal?

A)

A bounded signal is always finite

B)

A finite signal is always bounded

C)

A bounded signal always possess finite energy

D)

A bounded signal is always zero outside a given interval

Correct Answer : Option (C) : A bounded signal always possess finite energy

Explanation : A bounded signal always possesses finite energy as a matter of fact. Mathematically on integrating it can be also shown that the energy of the bounded signal is finite while power is zero.
