Power and energy of discrete signal

WebIn general, signals can be classified into three broad categories, power signals, energy signals, or neither. Deterministic signals which are made up of sinusoids, are an example of power signals, which have infinite energy but finite average power. Random signals also have finite average power and fall into the category of power signals.
