Question
List out the advantages and limitations of frequency modulation.
Answer in Brief
Solution
Advantages of frequency modulation:
- Large decrease in noise. This leads to an increase in the signal-noise ratio.
- The operating range is quite large.
- The transmission efficiency is very high as all the transmitted power is useful.
- FM bandwidth covers the entire frequency range which humans can hear. Due to this, FM radio has better quality compared to AM radio.
Limitations of frequency modulation:
- FM requires a much wider channel.
- FM transmitters and receivers are more complex and costly.
- In FM reception, less area is covered compared to AM.
