A standard test for the operation of an FM system is to examine the output spectrum when modulated by a standard test tone. You're examining an FM broadcast tx modded by a 1kHz tone. Level of the tone is set to ensure that the 100Mhz carrier is deviated to a peak deviation of +/-75kHz.
What's the min BW containing 99% of power? (Do not use Carson's Rule, find amplitude of each sideband and sum).
What is occupied BW if modulating signal is now 7.5kHz?
Now compare to Carson's Rule Approximation.
