The amount of frequency deviation in FM signal depends on
a) Amplitude of the modulating signal
b) Carrier frequency
c) Modulating frequency
d) Transmitter amplifier
Answer:
a) Amplitude of the modulating signal
Explanation:
The amplitude of the modulating signal determines the degree of frequency deviation or fluctuation in the FM signal. As a result, the louder the sound, the greater the frequency variation in the carrier signal, and vice versa. The frequency deviation aids in establishing the FM signal’s bandwidth.
