Quizplus · Accepted Answer

Carson's rule states that the bandwidth required for FM and PM is approximately equal to two times the sum of the modulating frequency and the maximum frequency deviation. This is greater than the bandwidth required for AM, which is equal to twice the highest frequency in the modulating signal. Therefore, Carson's rule demonstrates that both FM and PM require greater bandwidth than AM.
