Problem 3: The carrier c(t) = 100cos(2p fct) is frequency
modulated by the signal m(t) =
5cos(20000pt) , where fc = 108 Hz. The peak frequency deviation is
20 kHz. Determine the
amplitude and frequency of all the signal components that have a
power level of at least 10% of
the power of the un-modulated carrier component.
Hint: The wide-band FM has frequency components, fc, fc+ fm, fc?
fm, fc+2 fm, fc?2 fm,
and so on. The amplitude of the...
