The power of an un-modulated carrier signal is 50 W and the carrier frequency is f c
Question:
The power of an un-modulated carrier signal is 50 W and the carrier frequency is fc = 40 Hz. A sinusoidal message signal is used to FM modulate it with index β = 10. The sinusoidal message signal has a frequency of 5 Hz. Determine the average value of xc(t). By drawing appropriate spectra, explain this apparent contradiction.
