A band-limited voltage signal is found to have the complex Fourier coefficients presented in the table below. Calculate the average power that the signal would supply a 4-Ω resistor.
n ω 0 | |cn | | θ n |
0 | 10.0 | 0° |
ω | 8.5 | 15° |
2ω | 4.2 | 30° |
3ω | 2.1 | 45° |
4ω | 0.5 | 60° |
5 ω | 0.2 | 75° |
