5. AM and FM Modulation Schemes

Try these first

1. 1.

   What does AM stand for?

   Hint

   Think about how it changes the carrier wave.

2. 2.

   What type of modulation is used in FM radio?

   Hint

   Remember, FM stands for frequency.

3. 3.

   What does AM stand for?

   • Amplitude Modulation
   • Amplitude Model
   • Amplified Modulation

   Hint

   It’s about how the amplitude of the wave changes.

4. 4.

   Is FM more resistant to noise than AM?

   • True
   • False

   Hint

   Think about how each modulation affects signal clarity.

5. 5.

   A radio station wants to broadcast a long-distance coverage. Should it choose AM or FM? Justify your answer.

   Hint

   Think about the trade-offs between range and sound quality.

6. 6.

   Design a communication system that could potentially integrate both AM and FM. What would be the advantages of such a system?

   Hint

   Consider diverse scenarios needing different qualities.
