What does the power of a signal mean?

The power of a signal is the sum of the absolute squares of its time-domain samples divided by the signal length, or, equivalently, the square of its RMS level. The function bandpower allows you to estimate signal power in one step.

What is the power of an energy signal?

A power signal has infinite energy and an energy signal has zero average power.

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.

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

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.
