Question
The amount of frequency deviation in FM signal depends on
- Amplitude of the modulating signal
- Carrier frequency
- Modulating frequency
- Transmitter amplifier
Solution
The amount of frequency deviation in an FM (Frequency Modulation) signal depends on two main factors:
-
Amplitude of the Modulating Signal: The frequency deviation in an FM signal is directly proportional to the amplitude of the modulating signal. This means that if the amplitude of the modulating signal increases, the frequency deviation of the FM signal also increases, and vice versa.
-
Modulating Frequency: The frequency deviation in an FM signal is also directly proportional to the modulating frequency. This means that if the modulating frequency increases, the frequency deviation of the FM signal also increases, and vice versa.
The carrier frequency and transmitter amplifier do not directly affect the frequency deviation in an FM signal. The carrier frequency is the frequency of the unmodulated signal and the transmitter amplifier is used to increase the power of the signal before it is transmitted.
