Questions & Step-by-Step Solutions
In amplitude modulation (AM), what does the amplitude of the carrier wave represent?
Correct Answer: Information ki amplitude
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.
