Question: Which of the following is a disadvantage of Frequency Modulation (FM)?

Options:

Correct Answer: Complex receiver design

Solution:

FM requires a more complex receiver design compared to AM.

Which of the following is a disadvantage of Frequency Modulation (FM)?

Which of the following is a disadvantage of Frequency Modulation (FM)?

Step 1: Understand what Frequency Modulation (FM) is. FM is a method of encoding information in a carrier wave by varying its frequency.
Step 2: Compare FM with Amplitude Modulation (AM). AM varies the amplitude of the carrier wave, while FM varies the frequency.
Step 3: Recognize that FM signals are generally more resistant to noise and interference than AM signals.
Step 4: Identify the disadvantage of FM. FM requires more complex technology and design for the receiver to decode the frequency changes accurately.
Step 5: Conclude that the complexity of FM receiver design is a disadvantage compared to the simpler design of AM receivers.
