4. Is e -| t a power or energy signal?

How do you know if a signal is energy or power signal?

If x(t) has 0 < E < ∞ and P = 0 , then it is a energy signal, where E is the energy and P is the average power of signal x(t). The signal which has finite average power and infinite energy is called as power signal.

What is power signal example?

Power Signal:

Signals whose total power is finite and non-zero. The energy of the power signal will be infinite. Example: Periodic sequences like sinusoid. A sinusoidal signal has finite, non-zero power but infinite energy.

What is an energy and power signal?

A power signal has infinite energy and an energy signal has zero average power. Transient (finite duration) signals are energy signals while periodic signals are power signals.

Is e -| t a power or energy signal?

Signals having finite duration and finite amplitude and signals having infinite duration with their value tending to zero as t->Infinity or in general they are Energy Signals.
