Question

Find the power for the given signal x(t) = sin 80 using MATLAB. Check

whether x(t)=u(t) is energy signal or power signal.​

Answer 1

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.
