5.1. AM (Amplitude Modulation)

Try these first

1. 1.

   What does AM stand for in communications?

   Hint

   Think about the other modulation type—FM.

2. 2.

   Name one application of AM.

   Hint

   What comes to mind when you think of radio?

3. 3.

   What is the main advantage of using Amplitude Modulation?

   • High fidelity
   • Cost-effective
   • Increased bandwidth

   Hint

   Think about the cost of equipment.

4. 4.

   True or False: Amplitude Modulation (AM) is less susceptible to noise than Frequency Modulation (FM).

   • True
   • False

   Hint

   Recall what we discussed about noise in our sessions.

5. 5.

   If a radio station transmits at a frequency of 1 MHz using AM, what would be the impact of atmospheric electrical storms on the broadcast quality?

   Hint

   Consider how weather affects electrical signals.

6. 6.

   Given that FM has better noise resistance than AM, discuss potential scenarios in which AM might still be preferred.

   Hint

   Reflect on situations where ease of access matters.
