WebJul 8, 2024 · For a signal of the form: x (t) = Acos (ωt + φ) the average power is the average value of x² which is A²/2 (see point 2, above). But for x (t) = 5 + 10cos (100t + π/3) you cannot take the average power to be A²/2 because of the constant term (5). For …
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 $$\overline{x^2(t)}=10^2\cdot \frac12 + 5^2\cdot\frac12=62.5$$
