Amplitude Modulation:
Amplitude modulation (AM) is a type of modulation where the amplitude of the carrier wave is varied in proportion to changes in the amplitude of the modulating wave. This allows the modulating wave to be superimposed on the carrier wave, resulting in a new signal that contains both the original information and the high-frequency carrier wave.
Superimposing Modulating Wave:
In AM, the modulating wave is superimposed on a high-frequency carrier wave by varying the amplitude of the carrier wave according to the instantaneous amplitude of the modulating wave. This process allows the information signal to be carried by the carrier wave, which can then be transmitted over long distances without losing the original signal.
Transmitting Information:
By superimposing the modulating wave on the carrier wave in AM, the original information signal can be transmitted efficiently and effectively. The high-frequency carrier wave helps in carrying the signal over long distances and through various mediums.
Advantages of AM:
1. Simple to implement and widely used in broadcasting.
2. Efficient use of bandwidth compared to other modulation techniques.
3. Suitable for transmitting audio signals over radio waves.
Conclusion:
Amplitude modulation is a modulation technique where the modulating wave is superimposed on a high-frequency carrier wave by varying its amplitude. This allows for the efficient transmission of information signals over long distances, making it a popular choice for broadcasting and communication applications.

In Amplitude modulation, the modulating wave is superimposed on a high-frequency carrier wave such that the amplitude of the modulated wave varies as the amplitude of the modulating wave. The frequency of the modulated wave is equal to the frequency of the carrier wave.
