|---|---|
| Metrics for Continuous-time Signals | |
| CT signal energy | $ E_\infty=\int_{-\infty}^\infty | x(t) |^2 dt $ |
| 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 \, $ |
