In amplitude modulation (AM), what does the amplitude of the carrier wave represent?
The frequency of the modulating signal
The phase of the modulating signal
The information signal
The power of the carrier wave
In AM, the amplitude of the carrier wave varies in accordance with the amplitude of the modulating signal, which carries the information.

Q
Q: In amplitude modulation (AM), what does the amplitude of the carrier wave represent?
Solution: In AM, the amplitude of the carrier wave varies in accordance with the amplitude of the modulating signal, which carries the information.
Steps: 5
Step 1: Understand what a carrier wave is. A carrier wave is a steady wave that carries information.
Step 2: Know that amplitude refers to the height of the wave. In this case, it means how strong or loud the wave is.
Step 3: Learn that in amplitude modulation (AM), the information we want to send (like music or voice) is added to the carrier wave.
Step 4: Realize that the amplitude of the carrier wave changes based on the information signal. When the information signal is strong, the amplitude of the carrier wave increases.
Step 5: Conclude that the varying amplitude of the carrier wave represents the information being transmitted.
