1.	Which of the following determines carrier deviation in frequency modulation?(a) modulating voltage(b) modulating frequency(c) frequency deviation(d) modulating phaseThe question was posed to me during an interview.This interesting question is from Phase Shift Method topic in section SSB Modulation of Analog Communications
Answer» RIGHT CHOICE is (a) MODULATING voltage For explanation: In frequency modulation, frequency of CARRIER varies with the modulating voltage. In frequency modulation, it is modulating voltage that is responsible for DEVIATION of the carrier.
