Which of the following is a disadvantage of Frequency Modulation (FM)?
  1. Less bandwidth
  2. More noise immunity
  3. Complex receiver design
  4. Simple implementation

Questions & Step-by-Step Solutions

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.
