CTS: Energy and Power Signals Prepared by: Engr. Riza Carmela M. Pineda ENERGY SIGNALS a signal with finite energy has a zero power since averaging of finite energy over infinite time yields zero energy all time-limited signal of finite amplitude are energy signals examples of energy signals include one-sided or two-sided decaying signals and damped sinusoids ENERGY SIGNALS x(t) is an energy signal if 0 < E < ∞, so P = 0 POWER SIGNALS Some signals have infinite energy. In that case, we may use the concept of average signal power. x(t) is an power signal if 0 < P < ∞, so E = ∞ POWER SIGNALS - signals with finite power posses finite (non-zero) average power and infinite energy time-unlimited signal equally distributed energy over time PPOPERTIES of POWER SIGNALS 1. Periodic signals are power signals but vice-versa is not true. 2. Power (average) = 𝑅𝑀𝑆 2 Thank you . . .
