Solution and Explanation
The FM (Frequency Modulation) modulator is used in the audio section of a TV transmitter. In television broadcasting, audio signals are modulated using frequency modulation (FM), while video signals are modulated using amplitude modulation (AM), specifically vestigial sideband AM.
FM is preferred for audio because it provides better noise immunity and higher fidelity for sound transmission.
