WebThe modulated carrier wave then carries the information from the transmitting radio to the receiving radio via their respective antennas. Two common methods of modulating carrier waves are amplitude modulation and frequency modulation. Amplitude Modulation (AM) WebWaves carry energy by the motion of something causing the motion of something adjacent to it. For example, the forward motion of water molecules causing the forward motion of …
