amplituudmodulatsioon
Amplituudmodulatsioon, often abbreviated as AM, is a modulation technique used in electronic communication, most notably in the broadcasting of radio signals. In amplitudmodulatsioon, the amplitude of a carrier wave is varied in proportion to the message signal that is to be transmitted. The carrier wave is a high-frequency signal that is easy to transmit over long distances. The message signal, which contains the information to be sent, is typically a lower-frequency audio signal.
The process of amplitudmodulatsioon involves combining the carrier wave and the message signal. This combination results
Amplituudmodulatsioon is relatively simple to implement and requires less complex circuitry compared to other modulation schemes
