At this point, the modulated carrier wave can be coupled to a transmitting antenna. The shape and dimensions of the antenna are such that the carrier signal is converted into electromagnetic radiation.

WebModulation is the process by which information is encoded from a message source in order to optimize it for transmission. Frequency Modulation (FM) is the encoding of information in a carrier wave by changing the instantaneous frequency of the wave. FM technology is widely used in the fields of computing, telecommunications, and signal processing.
