Question

an energy signal can never be a power signal true or false

Answer 1

Answer is TRUE

• Energy signal and Power signal are two different categories under signal classification.
• Energy signal is a signal that has a finite energy and an average power of zero.
• Power signal is a signal that has an infinite energy and a finite average power.

These qualities shows that an energy signal cannot be a power signal.

Answer 2

For a signal to be an energy signal it must have power zero.

On the other hand, for a power signal to be energy signal the energy value should be infinity.

From this, we can conclude that an energy signal can never be a power signal. So, the statement is true.
