Power of a Discrete time signal

Power of a Discrete time signal

Power (sometimes referred to as average power) The power of a discrete-time signal x[n] is Px=limN→∞12N+1N∑n=−N|x[n]|2.

What is the power of a signal?

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 a discrete-time signal?

A discrete-time signal is a sequence of values that correspond to particular instants in time. The time instants at which the signal is defined are the signal's sample times, and the associated signal values are the signal's samples.
