Example.4: A 100 MHz un-modulated carrier delivers 120 Watts of power to a load. The carrier is frequency modulated by a 3 kHz modulating signal causing a maximum frequency deviation of 9 kHz. This FM signal is coupled to a load through an ideal Band Pass filter with 100MHZ as center frequency and a variable bandwidth. Determine the power delivered to the load when the filter bandwidth is: (a) 2.2 kHz (b) 10.5 kHz.
