WebFeb 1, 2024 · 1 Answer. Sorted by: 1. To calculate the energy of a continuous signal you use the equation: E ∞ = ∫ − ∞ ∞ x ( t) 2 d t. and for the power: P ∞ = lim T → ∞ 1 2 T ∫ − T T x ( t) 2 d t. If your signal has finite power ( 0 < P < ∞) then it's a power signal. If the signal has finite energy then it's an energy signal ... Web$$\overline{x^2(t)}=\frac{1}{2T}\int_{-T}^T x(t) ^2dt$$ Note that \$\cos^2 x=\frac12 (1+\cos(2x))\$ and \$\sin^2 x=\frac12 (1-\cos(2x))\$. So after integrating over one period, the terms with double frequency and also the cross-term cancel out. So you finally get for the power $$\overline{x^2(t)}=10^2\cdot \frac12 + 5^2\cdot\frac12=62.5$$
