A transmitter encodes a message onto electromagnetic waves … WebHow do radio waves carry information? The basic principle is simple. At one end, a transmitter “encodes” or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and ‘decodes’ it back to the desired form: sounds, images, data, etc.
