Questions & Step-by-Step Solutions
Which of the following is a disadvantage of frequency modulation (FM) compared to amplitude modulation (AM)?
Correct Answer: FM requires a larger bandwidth than AM.
Step 1: Understand what frequency modulation (FM) and amplitude modulation (AM) are. FM changes the frequency of the signal, while AM changes the amplitude (strength) of the signal.
Step 2: Learn about bandwidth. Bandwidth is the range of frequencies that a communication system can use to transmit information.
Step 3: Compare the bandwidth requirements of FM and AM. FM typically requires a larger bandwidth than AM to transmit the same information.
Step 4: Recognize that needing more bandwidth can be a disadvantage. In some communication systems, having limited bandwidth can make it difficult to transmit signals effectively.
Step 5: Conclude that the larger bandwidth requirement of FM compared to AM is a disadvantage in certain situations.
