Signal Metrics Definitions and Formulas
Metrics for Continuous-time Signals
(info) CT signal energy	$E_\infty=\int_{-\infty}^\infty \| x(t) \|^2 dt$
(info) CT signal average power	$P_\infty = \lim_{T \to \infty} \frac{1}{2T} \int_{-T}^{T} \left \| x (t) \right \|^2 \, dt$
Metrics for Discrete-time Signals
DT signal energy	$E_\infty=\sum_{n=-\infty}^\infty \| x[n] \|^2$
DT signal average power	$P_\infty = \lim_{N \to \infty} \frac{1}{2N+1} \sum_{n=-N}^{N} \left \| x [n] \right \|^2 \,$
