Answer:
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 ba.nd.po.w.er allows you to estimate signal power in one step .
Assume for a moment that the function, x, given by the OP represents a voltage. Then the formula is computing mean square voltage over the interval from t=1 to t=T. ...
Generally, in the world of signal processing, power is the square of the signal.
