An FM transmitter has a carrier frequency of 220 MHz. Its modulation index is 3 with a modulating frequency of 5 kHz. The total power output is 100 watts into a 50 ? load.
(a) What is the deviation?
(b) Sketch the spectrum of this signal, including all sidebands with more than 1% of the signal voltage.
(c) What is the bandwidth of this signal according to the criterion used in part (b)?
(d) Use Carson's rule to calculate the bandwidth of this signal, and compare with the result found in part (c).
