Question
Which statement is true regarding Frequency
Modulation(FM)?Solution
In Frequency Modulation (FM), the carrier’s frequency changes according to the instantaneous amplitude of the message signal, while the amplitude of the carrier remains constant . This makes FM less susceptible to noise compared to Amplitude Modulation (AM), since most noise affects amplitude. Although frequency is the main varying parameter, phase is indirectly related to frequency change, but the amplitude stays fixed. This is why FM provides better sound quality and higher noise immunity, making it widely used in radio broadcasting.
