1.	Carson’s rule is used to ________(a) calculate Bandwidth of FM signal(b) calculate SNR of FM signal(c) determine the carrier frequency(d) calculate Figure of merit of FM signalI had been asked this question in an internship interview.This interesting question is from Phase Shift Method topic in division SSB Modulation of Analog Communications
Answer» Correct choice is (a) calculate Bandwidth of FM signal To explain I WOULD say: According to Carson’s rule, the required bandwidth is TWICE the sum of the maximum frequency deviation and the maximum modulating signal frequency or B = 2(FD + fm)Hz.
