The carrier c(t) = 100 cos( 2mf.t) is frequency modulated (FM) by the message signal m(t) = 5 coS( 20000rt), where f.= 100MH2. The peak-frequency deviation is 20 kHz. The modulated signal is a wide-band FM. 1. Determine the amplitude and frequency of all signal components that have a power level of at least 10% of the power of the unmodulated carrier component. 2. From Carson's rule, determine the approximate bandwidth of the FM signal.

COurse: Communication Systems 

The carrier c(t) = 100 cos( 2nf.t) is frequency modulated (FM) by the message signal m(t) = 5 cos( 20000rt), where f.= 100MHZ. The peak-frequency deviation is 20 kHz. The modulated signal is a wide-band FM. 1. Determine the amplitude and frequency of all signal components that have a power level of at least 10% of the power of the unmodulated carrier component. 2. From Carson's rule, determine the approximate bandwidth of the FM signal.
